Leading to the Live Challenge

Lim Min, Lim Jeck and Lim Li have signed up for the Live Challenge scheduled for 22 Septermber (Saturaday). Their timings are:
Lim Min: 4 pm
Lim Jeck: 4 pm
Lim Li: 11 pm (who has to sign up for a later slot, as we have only 2 notebook computers with webcam at home).

Only for Week 5, the top 10 winners within the region will receive a prize pack of books and puzzles. After week 5, Lim Jeck's global rank is 1st of 3122 (tied with William Gan Wei Liang and Jaren Sta Maria). 

My kids are more interested in winning the top 7 and top 12 prizes (those underlined in Red), rather than the top 3 scholarship prizes.

Brilliant Challenge (Math Competition)

Take part in Brilliant Challenge!


Students solve problems online at their own pace and earn points over 5 weeks (maximum of 2300 points can be earned per week). New problems are released each week. At the end of the 5 weeks, students who have earned enough points will be invited to a Live Challenge conducted over Google Hangouts to compete for awards and scholarships. The official contest dates for the first Brilliant Challenge are Aug 13 - Sep 16. New problems sets will become available at the beginning of each week on Sunday (Singapore time is Monday morning), and the previous week’s problem sets will expire. However, students who join in the 4th (current week) and 5th week will still have ample opportunity to earn a sufficient number of points (i.e. 2200 points) to participate in the Live Challenge or take advantage of Master Classes and other prizes.

The Live Challenge will be held on Saturday, September 22, (Singapore time may be 1 day later) 2012. Students may choose from several time slots throughout the day, but may only participate once. The Live Challenge will be 1 hour in length. Brilliant coordinators will monitor students over webcam to maintain the integrity of the challenge.

As of now, Lim Jeck is ranked 1st (tie with 1 others) out of 2280 participants, after completing Week 4 contest. Lim Li is ranked 19th after completing Week 4 contest. The ranking is just for fun, it has no bearing on the Live Challenge. Lim Min only took part in Week 1 and 2 contests and she is not keen to continue with the contest.

To win the top prizes, only the Live Challenge points will be counted. Hence, you do not have any handicap even if you join only Week 4 and/or Week 5 contests. Join NOW!

National Day Rally 2012



At yesterday's National Day Rally 2012, our Prime Minister (PM Lee Hsien Loong) highlighted the achievements of our students at the recent International Math and Science competitions. He only mentioned International Biology Olympiad and International Mathematics Olympiad. I think the reason is, the media reported only these two in July, hence PM Lee did not pick up the notable achievements of the other Science olympiads. It also does not help that our local media has a propensity to publicise more on sports, and less on academic competitions. I shall help our PM to give our students their due recognition (words in bold are not part of PM Lee's speech, they are inserted by me :) ).

" .. our schools, students also do well across the board. And at the top this year, they shine at the international competitions. This year our team won the International Biology Olympiad, we hosted it, and our team won 1st place. Our student, Nol Swaddiwudhipong from RI, was 1st. At the International Mathematical Olympiad, a Singaporean student, Lim Jeck, from NUS High School of Math and Science, was the top student. He came in 1st, the only one to score full marks this year. At the International Physics Olympiad, our Singapore Team did extremely well, winning 4 Gold and 1 Silver medals. I am also proud that our International Chemistry Olympiad team had won 2 Gold and 2 Silver medals, and at the International Olympiad on Astronomy and Astrophysics, our Singapore team received 1 Gold and 3 Silver medals. .... It makes me proud that as a tiny red dot in the world map, we are able to achieve much ...."

International Physics Olympiad (IPhO) team - Joseph Kuan (RI), Huan Yan Qi (RI), Ding Yue (RI), Wayne Soo (NUS High) and Ang Yu Jian (NUS High)
International Chemistry Olympiad (IChO) team - Tan Zhi Yang (NUS High), Liu Aofei (RI), Rachel Lim  (RI) and Gerard  Low (RI)
International Olympiad on Astronomy and Astrophysics (IOAA) team - Kendrick Wong (NUS High), Ang Yu Jian (NUS High), Wang Ye (RI), Jee Kai Yen (RI) and Wayne Soo (NUS High) 
Kheng Leng (my niece, from Ngee Ann Polytechnic and now studying in NUS Year 1) was also mentioned by PM Lee.

CGMO 2012 Singapore Team Results and CWMI Selection Results

Left - NUS High team and right - RGS team 
The China Girls Mathematical Olympiad (CGMO) results were out. Singapore has won 3 Silver and 5 Bronze. The Silver medals are won by Tan Pin Lin and Jazlene Ong from NUS High and Zhang Boyu from RGS. This year, the cut off point for Gold is 108 (out of a total of 120 points) and for Silver is 75 (Surya missed it narrowly by a few points!). Heard that everyone who scored below 75 got a Bronze medal. Congratulations to all the girls!

Singapore will be sending 2 teams to the CWMI (China Western Mathematical Invitational) which will be held in Inner Mongolia from 26 to 30 September. In the past, students in the SIMO national team who have not participated in any IMO or who have not won a Gold before in previous years' CWMO (China Western Mathematical Olympiad) would take a selection test, from which 8 students are selected to participate in the CWMO typically held in October/November of each year. This year, there appears to be a change as students are going to CWMI instead (CWMI may be the new name for CWMO). The following 8 students have been selected:

1. Bay Wei Heng (HCI, Year 5)
2. David Lin Kewei (RI, Year 3)
3. Way Tan (NUS High, Year 4)
4. Teh Jiun Harn (RI, Year 4)
5. Yap Jit Wu (NUS High, Year 5)
6. Clarence Chew Xuan Da (NUS High, Year 1)
7. Liu Yi Jia (RI, Year 2)
8. Sheldon Kieren Tan (RI, Year 2)

Year 6 Term 3 Common Test Results

Lim Min's JC2 Term 3 Common Test Results
I think Lim Min did reasonably well for her Term 3 Common Test, scoring above 50th percentile for all her subjects. She could have done better for Chemistry and Economics though. Based on RI's yearly spectacular 'A' levels results, most students would score at least 2 grades above common tests and preliminary results. Hence I would think Lim Min should score at least 6 Distinctions (she has already obtained 2 Distinctions so far, in H1 Chinese and Project Work; she had sat for a H3 Math exam but result is pending) for her 'A' levels.

Olympic fever should extend to math contests

Olympic fever should extend to math contests
By Andres Oppenheimer The Miami Herald
aoppenheimer@MiamiHerald.com

What’s most interesting about the 100-country International Mathematical Olympiad (IMO) that took place last week in Mar del Plata, Argentina, was not that Asian students won the top prizes — they often do — but the fact that the event went virtually unnoticed in our part of the world.

While the July 4-16 math tournament got widespread media coverage in Singapore, South Korea, China and other Asian countries, it drew little attention in U.S. and Latin American media.

Our TV networks are already sending teams of reporters to cover javelin throws, archery and synchronized swimming competitions at the upcoming London Olympics, but few — if any — sent a correspondent to the Mar del Plata math tournament.

For the record, the 53rd annual IMO tournament of high school students was won by the six-member team of South Korea, which won six gold medals, followed by the teams of China (2nd), the United States (3rd), Russia (4th), Canada (5th), Thailand (6th) and Singapore (7th).

Among the Latin American countries, the best team was that of Peru, which ranked 16th, followed by Brazil (19th), Mexico (31st), Colombia (46th), Costa Rica (46th), Argentina (54th), Chile (59th), Venezuela (91st) and Cuba (95th).

Individually, the top prize was won by Lim Jeck, 17, of Singapore, who won a gold medal with a perfect score and became an instant media star in his home country.

Argentina, this year’s IMO host country, is a case study of how little attention is paid to education in many Latin American countries.

Most Argentine newspapers published only a few paragraphs about the math competition, if any, and most of it was buried in their society or culture pages. Neither President Cristina Fernández de Kirchner, nor the country’s education minister, nor any other top-level government official attended the event’s inauguration.

At a time when many international studies show that well-trained teachers are the single most important tool to improve countries’ education standards, garbage collectors and truck drivers in Argentina make much more money than teachers.

As I learned during a visit to Argentina a few weeks ago, truck drivers in that country make 2.8 times the minimum wage, garbage collectors 2.6 times the minimum wage, and teachers 1.3 times the minimum wage. A teacher working double shifts makes 2.59 times the minimum wage, still less than a truck driver or garbage collector.

Largely because of Argentina’s failure to evaluate its teachers and offer merit pay to the best qualified ones, education standards have plummeted in recent years.

The country, once among Latin America’s best educated ones, today ranks near the bottom in the international standardized PISA test of 15-year-old students, significantly behind Chile, Uruguay, Mexico, Colombia and other countries in the region.

In Mexico, while teachers make more than garbage collectors and truck drivers, a government crusade to improve education standards suffered a major blow earlier this month when only 30 percent of teachers attended a national teacher evaluation test. Earlier government plans to start a merit pay system for good teachers are now in limbo.

In case you are wondering whether there’s any relation between match and science education and countries’ economic growth, there is.

This year’s IMO winner South Korea, which was much poorer than virtually all Latin American countries only fifty years ago, last year registered 13,500 international patents for new inventions, whereas all Latin American countries together only 500, according to the U.S. Patent and Trademark Office.

In recent days, following President Barack Obama’s announcement that he plans to create an elite teachers corps that will pay professors of math and science an extra $20,000 a year, many Latin American educators stressed that without economic incentives and greater academic requirements, it will be hard to attract good teachers for Latin American schools.

My opinion: In the growing East vs. West battle for the best academic standards, we in the media share a large of responsibility for not putting education at the top of the public agenda.

There is nothing wrong with massive press coverage of the London Olympics. But when we focus our entire attention on sports competitions and virtually ignore math tournaments, we create only one kind of role models, and fail to glorify those who are the most likely to make the scientific discoveries that can improve our living standards or conquer diseases. It’s time to glorify Olympic math champions, just as we glorify Olympic swimmers.

Puzzles a thrill for maths whizz

Puzzles a thrill for maths whizz, by Matthias Chew

Love for numbers runs in the family for S'pore boy who topped international contest.

The obsession with mind-bending conundrums came early. A favourite childhood activity for Singaporean student Lim Jeck, who won the International Mathematical Olympiad last week, was to create puzzles for others to solve.

A peek into a jotter book belonging to the then 10-year-old reveals drawings of intricate mazes, ranging from squiggly lines to the three-dimensional. Now 17, his interest in unravelling puzzles has not abated. His favourite maths topics - geometry and combinatorics, which is the study of permutations and combinations - are relatively light on theories and formulae. To excel in those areas, one needs a logical mind and problem-solving skills.

His bent in navigating spatial and logical challenges helped propel Jeck to the top of the Olympiad in Argentina a week ago, beating 547 other pre-university students from 100 countries. He is the first Singaporean to do so. In the process, the National University of Singapore (NUS) High School student attained a perfect score, also a first for a Singaporean, and the only one in this year's contest, which attracts the brightest young mathematical minds from around the globe. But he is not done. He is aiming to compete again at next year's Olympiad, which will be the last he qualifies for, as he is due to graduate from NUS High next year as well.

The thought of repeating his feat does not faze him. Said Jeck: "I have one year to prepare for that and I will be ready for the challenge." With the contest setting the hardest questions in the last two years in both his pet topics, it played to the Year 5 student's strengths. Jeck came close last year, but missed out on a perfect score by a mere two points 'because I was not careful'. The result? He was second overall. Even then, it was the best showing by any Singaporean, till his first place finish this year.

An interview with the Lim family at their Stirling Road condominium yesterday revealed a gifted teenager who prefers computer games to cramming for tests. "He doesn't study too hard, but somehow manages to do well," said his mother, Madam Ng Bee Yong, 47, who runs an IT software firm with Jeck's father, Mr Lim Beng Cheng, 51. She said his As come in maths, physics, chemistry and computing, but he gets Bs and the occasional C for languages.

Jeck, however, is reticent in person, and it was his older sister, Min, who revealed that his other hobbies are reading and watching anime, and solving jigsaw puzzles. He was more forthcoming on e-mail. Asked who he would credit for developing his talent in maths, he singled out his family. "Without their guidance and support I wouldn't have come so far." His sisters, Min, 18, who is in JC 2 at Raffles Institution, and Li, 13, in Secondary 1 at NUS High, are both also mathematically inclined. The siblings are a fixture at local maths competitions, and Min also represented Singapore at the China Girls Maths Olympiad last year.

But like many boys his age, Jeck's mind these days is not on maths so much as the online game Minecraft. The multi-player game allows players to build structures, and Jeck exploits the game's lack of limits to create complex puzzles for his friends to manoeuvre out of. Indeed, playing Minecraft was the first thing Jeck did when he arrived home from Argentina on Wednesday.

While he has yet to decide where and what to study at university, one thing has not changed from when he was a little boy. He said he "would like to make maths, as well as computing, my career".

I think Mrs Lim Lai Cheng, the principal of RI, has generously donated another S$100 for each girl who has her hair shaved. There are 18 girls in total, which means she would have donated $1,800 to Children's Cancer Foundation. :)

Thanks to everyone who donated!

S'porean Boy's Perfect Score

Perfect win for S'pore boy in maths contest, by Matthias Chew 

NUS High School student Lim Jeck, 17, beat 547 others to clinch the top spot in this year's International Mathematical Olympiad. His perfect score of 42 was a first for a Singaporean, and the only one in this year's competition.

Lim Jeck has become the first Singaporean to clinch the top spot in a prestigious mathematics competition. The 17-year-old beat 547 other youngsters to rank first in this year's edition of the International Mathematical Olympiad in Mar del Plata, Argentina.

In the week-long contest which ended on Sunday, pre-university students attempted to solve six questions, each worth up to seven points. The top 9 per cent were awarded gold medals. Jeck's perfect score of 42 was a first for a Singaporean, and the only one in this year's competition. He pipped South Korea's Kim Dong Ryul, who scored 40, and Bobby Shen of the United States, who scored 39.

The National University of Singapore (NUS) High School student's win meant he went one better than last year, when he finished second. Then 16, he qualified for a gold medal along with three other teammates. The four-gold haul was Singapore's best showing to date, and the six-man team placed third overall. But this year, the Republic slipped to seventh out of 100 countries, with Jeck the only gold medallist. NUS High's Ling Yan Hao, and Raffles Institution's (RI) Ryan Kor and Lee You Jun took silver, while Lawrence Li from RI and Ang Yan Sheng from NUS High took bronze. South Korea came in first, with all six team members taking gold. China placed second while the US came in third. Singapore started taking part in the 53-year-old competition in 1988. Before last year, it had won gold only once, in 1996.

The Straits Times was unable to reach Jeck yesterday, as the Republic's team was in the midst of travelling home. They are expected to arrive in Singapore this afternoon. Jeck's father, businessman Lim Beng Cheng, told The Straits Times that this was the fourth time his son had taken part in the competition. He won bronze at his first attempt in 2009, when he was just 14, and silver in 2010. Medals are typically given only to the top 50 per cent of competitors each year.

Jeck discovered his love for maths in primary school, by solving maths problems posted by others on the Internet, said his father. He added: "We didn't train him at all, and none of our children have tuition." Besides Jeck, Mr Lim has two daughters - Lim Min, 18, who attends RI and Lim Li, 13, who attends NUS High. Mr Lim also praised NUS High for helping his son "build a very strong maths foundation". He added: "Jeck's next step is to start some maths research, but because he is still very young, we will move on very slowly and not put stress on him."
