A few more questions:

1- "GMATprep question bank", how big is it? cCan you compare it with actual GMAT question bank.
For example if on test day, the questions are drawn from a 5000-question bank, in GMATPrep the question bank is just 200 or something like that.


2- Is there a pattern for questions?
I know about the "intermingled" part of questions but do they appear on a pattern?

I'm asking this because some students(which i believe have to much time on their hands) have taken GMATprep for a few times. They've started comparing their quizzes with each other and apparently! have found a pattern in the way questions are asked.

This is the pattern for verbal section:
*The first number is the question number, the alphabetics are for sentence correction(SC), Critical erasoning(CR) and reading comprehension(RC)

1 SC
2 SC
3 CR
4 SC
5 CR
6 RC
7 RC
8 RC
9 CR
10 SC
11 SC
12 CR
13 SC
14 SC
15 RC
16 RC
17 RC
18 CR
19 CR
20 SC
21 SC
22 SC
23 RC
24 RC
25 RC
26 RC
27 CR
28 CR
29 SC
30 CR
31 SC
32 SC
33 RC
34 RC
35 RC
36 SC
37 SC
38 CR
39 CR
40 CR
41 SC


Does such a pattern exist in actual GMAT? Or this pattern is just designed for GMATprep so that GMAC can deliver a small sized practice source that is close to actual test?

Hello, Mehrabounr. I certainly understand your interest in learning more about our test question algorithm. The details you are requesting are not publicly available, nor will knowing them help students prepare for the GMAT exam. The GMAT computer adaptive test is designed to assess reasoning abilities. There aren't any shortcuts to improving your score without improving your reasoning skills, so the best way to score well on the exam is to study the material being tested, not the test algorithms! Good luck on your wiki, and if you have any other questions, please feel free to reach out.
