(3) How many mistakes can I afford in each section ?
Now, this is a slightly tricky question as it is not just the number of mistakes per se, but also 2 other factors which need to be considered:
1. Frequency of the mistakes: If you get questions wrong one after the other, you are in greater risk than if you distribute your mistakes over a range. For example, lets say, from questions 21 to 30 there are 2 candidates X and Y and their frequency of mistakes is: X marks the wrong answers for questions 22, 26 and 29, while Y marks the wrong ones for 23,24,25. Then Y would be penalized heavier than X.
2. Position of the mistakes: Has been said a gazillion times before, but the first 10 odd questions have a greater variation/fluctuation while assessing your score than the questions towards the end. Think about it. If you want to guage a person in an interview you start out asking the “average” questions if he cannot answer those, you would immediately drop down to the “basic” ones and it would be a long time before you could throw anything challenging at him. Whereas if he answered all the average ones you would pose him the “difficult” ones and it would be a long, long series of wrongs answers before you get fed up and start asking him “basic” questions.
However, it is possible for very high scores (read as “very few mistakes”) to show with a fair degree of accuracy what the association between mistakes and RAW scores. The following data I found from the net to fairly representative:
Verbal
# mistakes score
0-1 51
2-4 50-45
5-7 40-44
8-13 39-35
Quant
# mistakes score
0-2 51
3-5 50
6-10 49
11-14 48
So you can still score over 90%ile in Quant after getting 12 quant ques wrong..
