Playing Piano
This is posted by LL ™ (press ctrl and 0153 to get the ™)
Hi. This is the 2nd song I learnt. It is called Hokage's Funeral from Naruto. I am in piano grade zero because I have never learnt piano from any teacher. There were some mistakes I made, but I was too lazy to retake after so many NGs. Other songs that I have learnt to play include: Itsumo Nando Demo from Spirited Away, Sadness and Sorrow from Naruto, Super Mario Brothers: Underwater Theme, 月亮代表我的心 and Tsuna Awakens from Hitman Reborn.

Mistakes in Olympiad Maths Trainer 6 Book
This is posted by Lim Li ☺☻
My mother bought this book from Popular Bookstore for me to practise last year. I found many mistakes. Now that I am so free (PSLE is over!), I will type out some of the mistakes. My comments are in Red.
Week 2 Qn 5.
(a) Choose any three letters from a, b, c and d. In how many ways can we arrange these letters?
(b) A teacher wants to choose a captain and a vice-captain among 12 volleyball players. In how many ways can he do so?
Answer: (a) 4A3 = 4 x 3 x 2 = 24
(b)12C2 = (12 x 11 )/(2 x 1 ) = 66
(a) Should be 4P3
(b) Captain and vice-captain is different person, should be 12P2
Week 5 Qn 2. In a mathematics quiz, Fredric answered 1/9 of the questions wrongly. Paul answered 7 questions correctly. The number of questions that both of them answered correctly was 1/6 of the total number of questions. How many questions were there in the quiz?
Answer. 18
First of all, from the 3rd statement, 1/6 of the total number of questions, one would naturally assume that it is the total number of questions in the mathematics quiz rather than the total number of questions both answered together, which is twice the amount. We also have to assume that all questions are answered correctly or wrongly. Logical interpretation of the question would lead to 36 as the answer.
Week 5 Qn 5. In the figure below, how many triangles can be formed using any three points as the vertice?
. . .
. . .
. . .
Answer. 64
The correct solution is 9C3=84, 84-8=76 Answer: 76
Week 6 Qn 3: For 1^2 + 2^2 + 3^2 + ... + n^2, we can compute n(n + 1) (n + 2) /6. Find the value of 1^2 + 2^2 + 3^2 + ... + 15.^2
The formula in the question is wrong. It should be n (n + 1) (2n + 1) /6
Week 7 Qn 1. Don and Andy have some marbles. If Don gives some marbles to Andy, the number of marbles that Don has is twice the number of marbles what Andy has. If Andy gives the same number of marbles to Don, the number of marbles that Don has is 4 times of what Andy has. How many marbles does each of them have at first?
If the question does not provide any number, how are we supposed to find the number of marbles each of them has? I think the question should be: "What is the least possible number of marbles each of them has at first?"
Week 10 Qn 6. An athlete ran up the staircase of a building as part of his training programme. If he ran up the building at first and then walked up the last 24 steps, it would take him 28 seconds. If he ran up the building at first and then walked the last 36 steps, it would take him 30 seconds. How many steps were there on the staircases?
It is an impossible question, which cannot be solved. Too little information is given. Assuming speed is integer, there will be 3 solutions, 72, 288, 720 steps. If speed is not integer, the number of steps can be any integer above something, 36 I think. Anyway, if you see the solution given, the first statement totally didn't make any sense, and the 2nd statement is even worse.
Other questions with mistakes that I am too lazy to type. Sorry, only people who have purchased the book will understand what I am typing.
Week 7 Qn 2:either the question should be unshaded or the answer should add a 200-85=115
Week 9 Qn 2: should write "only" for the 2 subjects e.g. 6 students like both mathematics and English only, instead of, 6 students liked both mathematics and English.
Week 10 Qn 1: the question says the number formed by the first 5 digits and the number formed by the last 3 digits is 68427 but the answer says 68247.
Week 13 Qn 5a: it says + but should be x
Week 14 Qn 2: firstly, the answer says 320/(64/48)=20. It should be 320/(64-48)=20. Secondly, you are assuming there is the same amount of chairs and tables, which is not stated in the question.
There are (a lot) more questions with mistakes, which I am even lazier to type.

PSLE Over!!!
This is posted by LL☺☻
PSLE is over!!!!( ! x a very big number) Now I can start to recycle all the stuff (no burning as it causes global warming). However, there is still HCL for those taking HCL, too bad for you :P.
How do I find each paper? Why am I asking myself? Because I am weird :)
[*very easy, ** easy, *** ok, **** hard, ***** very hard]
English [***] - easier than my school prelim exam but my English is VERY poor so I obviously did badly even if the paper is not difficult :(
Math [*] - too easy, I managed to check more than 3 times but unfortunately I did not spot a careless mistake in one of the questions - Paper 1 reading book question, I put 26 days when the correct answer should be 24 days :(
Chinese [***] - my teacher said it was considered a difficult paper as some questions were rather tricky :( I think I have made a few mistakes, they are not careless mistakes as I really am dumb
Science [**.5] - I completed the paper in about 1 hr 5 mins and have 40 minutes to check. As expected, I managed to find a few mistakes (since I am such a careless person) during checking.
Things to do after the PSLE:
1. hibernate
2. sleep
3. eat
4. sleep more
5. laugh at people who take HCL
6. play
7. tell everyone that 1+1=2
8. (same as 1)
9. do random things
10. go US before I'm 13 years old (note that US is not united states, hint: it is in Sentosa)

Invitation to the Faculty of Science, NUS
This is posted by LJ's mum.
After Lim Jeck has won an IMO gold medal, a number of well-meaning people suggested that he should consider pursuing his higher education in a top-ranking overseas university such as one of the Ivy League or Oxbridge universities. Personally, I am not in awe of overseas branded universities and I also do not think that our local universities are inferior to the overseas ones. As long as one works hard for his passion and has a positive attitude, he can shine in whichever university he goes, and in whatever vocation he undertakes after graduation. Since Lim Jeck is still about 4+ years away from enrolling in an university, there is still much time for him to think about where he wants to pursue his undergraduate studies.
He has recently received an invitation to apply for the Faculty of Science, NUS, when he is in his final year at NUS High (2 years later). The offer is quite attractive as he will be guaranteed at least a Kent Ridge Undergraduate Scholarship (bond-free) which provides full coverage of the annual tuition fees (which is about $5360 x 4 years, based on current year's fees for the Faculty of Science).
In my opinion, it is a good choice for Lim Jeck to join NUS after his studies at NUS High and after National Service. He has already completed two Year 1 NUS Math modules and is currently doing a Year 2 NUS Math module. By end this year he would have completed all his Math modules at NUS High, so next year onwards he would have more time to take additional NUS modules - either from the Faculty of Science or from the School of Computing. In NUS, there is a suitable double degree programme for him - Bachelor of Computing (Computer Science) and Bachelor of Science (Mathematics/Applied Mathematics). I think if he joins this programme, he should be able to get his double degrees (with honours) in less than 4 years.
Of course, ultimately the choice is his to make!

In the PSLE, the T-Score for each subject is calculated as T = 50 + 10 (raw mark of student - average mark of the whole cohort)/(standard deviation or spread of marks around the average mark). The PSLE Aggregate Score is the sum of the T-score of all 4 subjects. Clearly, at this juncture the average mark of the whole cohort for each subject and also the standard deviation are not known. Hence, I can only hazard a guess Lim Li's likely PSLE aggregate score. My estimation of the aggregate score is based on what Lim Min and Lim Jeck had scored in their Prelim Exams and their PSLE aggregate scores, and what Lim Li has scored in her recent Prelim Exam.
Lim Min's P6 Prelim Exam Results in 2006:
English 84
Chinese 91
Higher Chinese 75 (not included in Total score)
Mathematics 100
Science 94
Total score 369/400
PSLE aggregate score: 265, A* in Chinese, Mathematics and Science, A in English, Distinction in Higher Chinese.
2006 Highest PSLE score in Singapore: 281
Lim Jeck's P6 Prelim Exam Results in 2007:
English 79
Chinese 82
Mathematics 99
Science 94
Total score 354/400
PSLE aggregate score: 263, A* in Mathematics and Science, A in English and Chinese
2007 Highest PSLE score in Singapore: 294
Lim Li's P6 Prelim Exam Results in 2011:
English 72
Chinese 87
Mathematics 98
Science 88
Total score 345/400
My estimation for Lim Li's PSLE aggregate score is in the range 250-255. She is likely to score A* in Mathematics and Science, A in English and Chinese.
If this year's PSLE Mathematics paper is very tough, her aggregate score will probably be higher since Mathematics is her pet subject. However, if the Mathematics paper is very easy and English is very tough, then her aggregate score will likely be pulled down.

2011 PSLE Listening Comprehension
This is posted by LL
(note: I am writing from the iPad so there are some stuff that only those using apple things like iPhone, iPad and iPod can see)
PSLE Listening is over! Now I can throw away all my listening stuff or give them to my cousins. The English listening compre is okay but the Chinese one has one difficult question (question 5 which is about the main purpose of the retiring principal's speech). I put 2 but I think the answer should be 3 - to thank the students for organizing the previous day's concert. I think I should score full marks for English listening (20/20), but I got one wrong for Chinese listening (should score 18/20).

林捷（左）横扫新加坡数学比赛的高中组和公开组冠军，获得教育部兼国防部政务部长黄循财的赞赏。 （周柏荣摄）新加坡数学奥林匹克赛，国大数理中学学生称王
来源：联合早报2011年9月4日
国大数理中学的林捷独占鳌头，在新加坡数学奥林匹克比赛中，击败了1万多名参赛学生，横扫高中组和公开组冠军。
林捷（16岁）的数学知识不但在本地的学生之上，他也刚在7月摘下国际数学奥林匹克比赛亚军荣衔，昨天三度上台领奖，成为我国耀眼的数学明日之星。
而林捷对数学的兴趣早在他小学五年级时就培养起来。他的父母毕业自国大电脑科学系，相信在潜移默化中儿子也喜欢上数学，从小就玩拼图游戏、迷宫和魔幻方块（Rubik's Cube）。现在，林捷在温习数学功课时，也上数学网站，向网友发问数学题目，互相切磋。
他的母亲黄美蓉（46岁）受访时说：“有些孩子空闲时就拿故事书来读，林捷则会拿起iPad，玩数学游戏，上数学网站交朋友。”
教育部兼国防部政务部长黄循财昨天为百多名学生颁发奖状，肯定他们在新加坡数学奥林匹克比赛、新加坡数学研究计划比赛和国际数学奥林匹克比赛这三项比赛的表现。
今年，共有来自138所学校的1万零665名学生参加的新加坡数学奥林匹克比赛，是历来参与人数最多的一次。
真金不怕火炼，数理学科一直是国大数理中学、华侨中学和莱佛士书院的强项，这三所中学更在今年的比赛中，独占初中组、高中组和公开组的前三甲宝座。
而新加坡数学研究计划比赛今年则吸引了来自20所中学的55项研究计划，让学生在课堂外，通过新颖、有创意的方式接触数学。
颁奖礼上，得奖团队的学生讲解他们的研究计划，他们不仅通过斐波那契数列（Fibonacci Sequence）来解决电影售票员零钱不足的问题，也用量子物理学来确保自己能在井字棋（Tic-tac-toe）中取胜。
黄循财接受本报访问时说，新加坡的数学教育景观日益多样化。“所以我们才能够不断寻求突破，因为数学的教育方式不单是公式化的，也可以灵活运用。”
他解释，我国教育系统有类似国大数理中学的教育学府，专研数理学科，同时也有多项比赛和活动，让学生了解数学的乐趣。此外，数学比赛也越来越多样化，学校举办国际数学比赛，更推出新颖的数独（Sudoku）比赛。
新加坡数理学会副主席林杉认为，我国数理成果突出的其中一个原因是参与数理教学工作的人员的热情投入。他以协会的成员为例说，成员多数为数学老师和教授，他们都是出自于对数学的热忱，在工余时间志愿参加学会的各项活动。

CGMO 2011 News on Tamil Murasu
This is posted by Lim Min's mum.
The girl in the picture is Surya Mathialagan, a Year 2 student from NUS High. She was interviewed by Tamil Murasu (the Tamil newspaper under SPH) on her CGMO achievements.
An English translation of the above article can be found in Edvantage website - Surya scores at maths Olympiad
EIGHT students - from Raffles Institution, NUS High and Raffles Girls' School - did Singapore proud at the recent China Girls Mathematical Olympiad.
They won one gold, two silver and four bronze medals at the event held in Shenzhen from July 30 to Aug 3... a vast improvement from last year's tally of one silver and four bronze medals.
NUS High School of Mathematics and Science Year 2 student Surya Mathialagan was the only Indian in the group. And she came home with a bronze medal.
A veteran of such maths Olympiads - she has been taking part in such competitions since she was in Primary 5 - this is Miss Mathialagan's first international medal. And the joy was evident when she told Tamil Murasu: "It gives me a lot of satisfaction when I solve tough mathematical problems."
The China Girls Mathematical Olympiad was introduced in 2002 as a domestic event but various countries have been invited to take part since. It comprises four questions that have to be completed in four hours. In Singapore, students undergo tests to qualify for the team representing the nation at the Olympiad.
Miss Mathialagan, who prepared for this Olympiad by tackling various mathematical questions for a minimum of six hours in the week leading up to the event, is now setting her sights higher. "I want to work harder and take part in the International Mathematical Olympiad. Once I do that, I want to win a medal and make Singapore proud," she said.

2011 PSLE Orals
This is posted by LL
Orals are finally over ☺. Now we can throw away all our oral stuff.
I know my drawings fail. This is the picture of the Chinese oral (1st day) stickman version:
I said that it was a classroom （课室）, but my mother said that it was a students' corner （学生园地/学习角落） . The thing at the top right is a notice board （布告栏/布告版）and the paper is torn. The girl on the left is hitting the other girl with a bundle of papers. Conversation topic is about small group discussion （小组讨论/小组活动）(I am not sure), and "what have you learnt?"
This is the picture of the English oral (2nd day) stickman version.
This is a clinic. The man at the left is giving a $50 note to the cashier. The girl in the middle is sobbing uncontrollably and her hand is bandaged; the door says the doctor's name but I forgot. The two boys at the bottom right are fighting over a toy car. Conversation topic is "Have you been to the clinic? Tell me about your experience."

CGMO 2011 Singapore Team Results
This is posted by Lim Min's mum.
The CGMO Day 1 competition was on Monday, Day 2 yesterday, the marks were released at 11.30 pm last night (that is fast marking!) and the medal results revealed at about 11 am this morning.
Singapore's Results:
Aidi - 87 marks (Gold)
Pin Lin - 63 marks (Silver)
Lim Min - 60 marks (Silver)
Surya - 42 marks (Bronze)
Lydia - 36 marks (Bronze)
Si Ying - 33 marks (Bronze)
Belinda - 30 marks (Bronze)
Dorette - 18 marks (no medal, 加油for next year!)
Note: each day 4 qns, each qn carries 15 marks, total 120 marks. All marks awarded are in multiples of 3.
Cut-off marks for Gold, Silver and Bronze are 72, 48 and 21 respectively. It seems that this year the organiser decided to give out more medals (I heard, about 140 out of about 200 participants won medals), probably to make more people happy :)
Singapore has won a total of 1 Gold, 2 Silvers and 4 Bronzes. This is a commendable improvement over last year's haul of 1 Silver and 4 Bronzes :)

Pin Lin - 63 marks (Silver)
Lim Min - 60 marks (Silver)
Surya - 42 marks (Bronze)
Lydia - 36 marks (Bronze)
Si Ying - 33 marks (Bronze)
Belinda - 30 marks (Bronze)
Dorette - 18 marks (no medal, 加油for next year!)
Note: each day 4 qns, each qn carries 15 marks, total 120 marks. All marks awarded are in multiples of 3.
Cut-off marks for Gold, Silver and Bronze are 72, 48 and 21 respectively. It seems that this year the organiser decided to give out more medals (I heard, about 140 out of about 200 participants won medals), probably to make more people happy :)
Singapore has won a total of 1 Gold, 2 Silvers and 4 Bronzes. This is a commendable improvement over last year's haul of 1 Silver and 4 Bronzes :)

金牌数目历来最多
金牌数目历来最多
陈紫筠(2011-07-27)
| 我国队伍在这项比赛中多年一直徘徊于20至29名内，去年获得第22名，而表现最好的一次是2005年，排世界第14。 这次除了在排行榜上取得大跃进外，获得的金牌数目也是历来最多的。自90年代初取得第一面金牌后，我国队伍十几年来与金牌无缘，今年六名参赛的学生共夺下四面金牌，一面银牌和一面铜牌。其中有三名学生在个人排行榜上名列第二、四以及六名。 这支为国争光的队伍由英华中学、莱佛士书院（高中部）以及新加坡国立大学数理中学的六名学生组成，他们年龄介于16至18岁。 我国从1988年就派队参赛，新加坡数理协会副主席王金富博士说，每年派出的队伍平均获得五面奖牌，而今年的成绩是最令人振奋的。 他受访时说，表现好的原因是小学数学课程奠定的稳固基础，以及给予有特别才能学生的额外培训，要取得更多突破是指日可待的。 金牌得主是英华中学的洪捷君、国大数理中学的林捷以及莱佛士书院（高中部）的丁岳和关俊杰。国大数理中学的洪延昇和莱佛士书院（高中部）的许崇乐，则分别获得银以及铜牌。他们除了丁岳是新加坡永久居民外，都是土生土长的新加坡人。
世界亚军林捷（16岁）对自己的成绩感到意外，他说：“一些题目比筹备时接触过的困难许多，我花了不少时间解答，几乎是在最后几分钟才完成。有如此表现，我感到十分高兴。此外，这也是一次很好的经验，让我有机会与来自德国、中国等国家的优秀选手切磋。” 林捷为比赛下了一番苦功，除了接受规定训练外，也在家里自习。他毕业自女皇镇小学，有多次参加各项数学比赛的经验，这也是他第三次参加奥数。 率领队伍出征的国大数学系副教授黄恩来说，林捷解答问题的技巧纯熟，思路清晰有条理，他只差两分就满分。 由教育部、新加坡国立大学以及新加坡数理协会成立的筹备小组，一年前就紧锣密鼓为比赛作足准备。先是通过全国性奥林匹克比赛挑选出20名学生接受每周一次的训练，再从中挑选出六名学生代表国家出赛。 洪延昇（17岁）说，比赛前的筹备功夫不简单，他们两个月里每星期六天、每天八小时的训练，除此之外，还得参加两周的“闭门”密集训练营。 这项一年一度的国际比赛，于本月16日至24日在荷兰首都阿姆斯特丹举行，共有101个国家的564名代表参加，他们都在20岁以下。这次比赛中，共颁发了50面金牌、100面银牌以及150面铜牌。 | ||

IMO 2011 Question 6
This is posted by LJ's mum.
Lim Jeck has returned home safely this morning - this certainly beats all the accolades that he has won in the IMO :) After an exhausting 12.5-hr flight, he is now sleeping soundly. After all these euphoria at the IMO, the next few weeks he will have rough sledding playing catch-up with all the missed school lessons. :(
I think it is going to be a challenging task for Singapore to maintain her top positions (country rank 3rd and individual ranks 2nd, 4th and 6th) next year. Out of the 5 team members who should qualify for next year's IMO again, 2 are likely to move to other Science Olympiads. This year's questions are favourable to the team, next year's questions might not be.
Anyway, back to my main topic, the Question 6 which stumped many contestants except for the 6 (Lim Jeck being one of them) out of a total of 564 contestants, who could solve it completely.
The IMO 2011 questions.
Lim Jeck's solution for Question 6.
