The 2020 results is from this forum and the official website. It contains anonymous results for all the candidates who took the exam in 2020. It has the birth month, Maths, English and Total (standardized?) score.

I have done some data visualization and trying to post some figures. I hope to get more discussions on how well I should prepare my son for the test and how competitive is it to get a place.

I am trying to find a free online host for the figures I shown below. if you can't see the figure, please let me know.

**Birth month for all candidates and candidates with scores >=235.****English, Maths and Total scores count.****English vs Maths scores and threshold 235 and 232.**This is an interesting figure and I am trying to understand it.

Cumulative counts from top scores. This seems to suggest there are almost 300 candidate just get 3 or less questions wrong in Maths. To be safe,

**candidate should get at most 2 questions wrong out of 50 maths questions!** The English results are more diverse and I am not sure whether it is because more aged standardization adjustment is done on English scores than the Maths scores. Suggestions are very welcome.

For those with total scores >=235, some Statistics (min, max, median, 25% 75% quantile, outliners) detailed results over birth month.
