Kaplan gmat test

Question

I scored V31 in gmatprep practice test and V37 in kaplan gmat practice test.
In both tests, i answered 18 questions incorrectly. Why is there so much difference in score in both tests with same accuracy? Is kaplan test not evaluating my score correctly?

Hi Vjtayal08 , GMAT Algorithm calculates the score on the basis of DIFFICULTY rather than NUMBER of attempted questions. It is possible to get the same score even after marking more questions correct. please see the below data from REAL GMAT EXAMS and your doubt should be clear. Notice that a guy who gets 23 questions correct gets a Q49 and the one who gets 21 questions correct also gets a Q49 but the same 21 gives a Q47 to someone else. variations in scores.png

Dear Vjtayal08 , I'm happy to respond.

I see that HKD1710 already gave you an excellent answer. I will add a few thoughts. Many GMAT student profoundly misunderstand the nature of the Computer Adaptive Test (CAT). The real GMAT uses an official algorithm, GMAT Prep uses essentially that same algorithm, and other test prep companies use algorithms approximating the GMAT model. I don't know whether the kaplan test you took was a CAT on the computer or a paper test: obviously, any paper test would not be adaptive. As HKD1710 said, what matter is the difficulty level, not merely the number right, as on a conventional test. The test adjusts to your level as you take it. The rough pattern is that as you get questions right, the subsequent questions get harder, and as you get questions wrong, the subsequent questions get easier: that is not the whole story, but the rough pattern. Thus, the test magically homes in on each test-taker's ability level and feeds that person questions right at that person's edge, so that the person is getting some right and some wrong throughout the test. The ironic result is that the person who gets a 450 and the person who gets a 750 probably get about the same number of questions right and wrong, but the difficulty levels are different: just about all the questions each person was doing was appropriate in difficulty level to that person's ability level. Thus, number of questions you got right or wrong is less than useless. It's all about the difficulty level. You can read more here: Computer Adaptive Testing on the GMAT Does all this make sense?

These guys already covered everything about the scoring method, but I'll add my .02 and say that my gmatprep and kaplan scores were very similar. Don't put too much thought into it, but you are probably in the 34ish range for verbal. It's pretty normal to be +- a few points from test to test even if you are at the same skill level

I guess i should work on high difficulty questions more now to score V38+
I want to score 700+ in actual gmat test
My quant is around Q47
