Everyone who is familiar with GMAT must be familiar with the term 'CAT'. And everyone, who knows about this artificial intelligence approach, comes to learn that it is a system, which tests the ability of the test taker by presenting questions of difficulty based on the level of previous answers. Almost every GMAT prep guide , no matter if it's online or hard copy,gives us a notion that if someone can make the first 10 questions correct his/her scores reach high . And the test takers should spent more time on the first 10 questions than the middle or last 10 to let the computer know that you're brilliant.
But , recently , I think I found a clue that makes this common explanation probably flawed. I just gave two tries with official GMAT prep software to check the "first 10 idea" and found that the this very common concept on CAT, which I myself considered as a Knewtonian theory, perhaps not correct.
Here is what I found.
Test 1 ----Quant 33----Verbal 23--scroe -570
Test 2-----Quant 44----Verbal28--Score--590
When reviewed the test at the end, most interestingly, I found that the
Test 1 : correct answers were like this--- Questions 1 to 11 all correct except 2 wrongs, question 12 to 27 all wrong except 3 correct answers and 28 to 37 all correct except 2 wrongs . So, in brief, out of first and last 20 questions I made only 4 incorrect , yet the score was 33.
Now the Test 2:
From question 1 to 11 all wrong except 4 correct, which are in this order- c-c-ic-ic-ic-ic-c-c-ic-ic,
From question 11 to 26 all correct except 3 incorrect (#14,22 and 24)
From 27 to 37 only 5 correct (27,30,31,32,33) and 6 incorrect including the last three.----but the score was 44.
I have test 2 record still in my prep review part, if someone wants , he or she is welcome to see.
I have no intention to put the entire prep course people in question regarding their so common 'focus on first 10 question" strategy-- but the actual and real GMAT prep does not agree on that. In test 1 you can see, making almost 8 questions correct out of 10 you can get score 33 , whereas only 4/5 correct answers in the first 10 and last 10 questions can give you score of 44.
I am not sure why. May be there are some explanations,and I welcome that , if any.But all I know now -- this is GMAT 'CAT' !!
Thanks

First ten is a mostly a myth, and is more likely to cause problems than create success.
See the summit write up for more info:

You can answer 70% correct and get a 700
You can answer 70% correct and get a 550
Strike rate alone is meaningless. You must consider strike rate with problem difficulty.
