Interesting observation - MGMAT CATs

While I was reviewing my MGMAT practice tests, I realized that all of the tests have exactly:

15 Sentence Correction questions
14 Critical Reasoning questions
12 Reading Comprehension questions

I looked at my timing and accuracy in each quarters:

Questions 1-10

I spent around 22 minutes and my accuracy is only 60% - weak starts.

- I think I spend a little more than I should be spending with the 10 questions and over think most of the questions

Questions 11-20

I spend most of my time in this quarter - average of 26 minutes (major timing problem, which affects the rest of the test )

- My average accuracy in this quarter is 70 %

Questions 21-30

- I feel kind of nervous in this third question and I tend to speed up
- Careless mistakes, and average accuracy down to 60 %
- Average time spent : ONLY 13 minutes!!
- It is interesting because I almost spend half of the time I spend in the 2nd quarter of the test and my accuracy rate is only down by 10 %

Questions 31-41

I continue to pay for my bad timing strategy in this last quarter and spend only 14 minutes

Stress is definetly more than the rest of the quarters

Accuracy is sadly down to 50 %

Very weak finish

Overall:

SC: 12/15 average
CR: 7/14 average - This is interesting because I used to believe that SC is my weak point. My OG accuracy is 93 % on CR, and 80 % on SC
SC: 7/12 average. Most of the incorrect answers are from 3rd and 4th quarter ( NO WONDER WHY!)

Overall score range: 32-40 with 34 average.

My quant scores are not bad : 50 average and I only scored 51 once! ( 75 minutes for MGMAT math questions is not plenty )

Any suggestions and tips are welcome.

Thanks,
