P6 Prelim Results and Expected PSLE Aggregate Score

This is posted by Lim Li's mum.

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* for Chinese, Mathematics and Science, A for English, Distinction for Higher Chinese.
Highest 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* for Mathematics and Science, A for English and Chinese
Highest 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* for Mathematics and Science, A for 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.

The PSLE aggregate score is calculated based on t-score (transformed-score) for each subject. Strictly speaking, there is no fixed maximum marks. However, to make things simple, you can assume that it is about 300 though it is not impossible to score more than 300 (so far it has not happened, the higest in PSLE history is 294). For 234, you can get into an Express stream.

Yes the overall marks is upon 400 just like your school exam. However the PSLE aggregate score is not. A quick estimation is to use your P6 prelim exam overall marks to multiply by 3/4. All the best to you in your PSLE next year :)

Hi Lim Jeck , I will like to find out how to calculate the PSLE Aggregat Score for PSLE for my son's result :

English = 88
Chinese = 92
Maths = 97
Science = 84
Total Score = 361/400
2011 Top Singapore PSLE Score = 283

How much will my son roughly score for his PSLE exam 2012 in he maintains this result?

Hope you can assist.

Hi Lim Jeck, do you think the cut-off point for Hwa Chong Institution this year would increase, or would it stay the same?
Hope you can assist.
