Few Months back:
I took two GMAT Prep CATs in Nov/Dec after I went through the MGMAT Strategy Guides the very first time. I scored a 620 and 620 if I remember correctly.
I did not review the questions then since the test back them would not save your answers and I intentionally did not want to review the exam as I knew I wanted to keep the tests for a 2nd attempt close to my test date.
I also took a MGMAT CAT then and scored a 640.
Now after preparing for 5 months, I downloaded the latest GMAT Prep 2.0 software and retook both the tests.
Test 1 - 720 (Q49, V40)
I did see a few repeats on test 1 (2 in Quant, vaguely remember reading a RC similar to one of the RCs that appeared. However, I didn't remember the questions etc for that RC. No other repeats in Verbal).
Test 2 - 720 (Q48, V40)
Quant - 1 question I recognized from the beatthegmat website article.
Verbal - 1 RC as well from either the OG or some other source. However, I didn't remember the questions at all and only very vaguely remembered the RC passage itself.
Today I took a MGMAT CAT and scored a 630 (Q41, V35)
I am utterly confused. I find the MGMAT CATs to be ridiculous difficult and they seem to score hard.
I am not sure if I should take the test in a weeks time or postpone. I feel like I should take the test and see what happens. Any advice please?
Neither algorithm will give you an accurate score though GMAT prep test is official. The algorithm and difficulty level of questions of GMAT prep test will not be the same as that of the actual GMAT but it is the best bet. A 2 question advantage (since you had already done them or seen them) is nothing in an adaptive test.
In my opinion, if you feel you are prepared, go ahead with the test. Hopefully the 630 is just an aberration (but make sure you analyze the test to see where you went wrong). Also, if you want to be sure, try out a bunch of 700 level official questions from the forum and see if you can do them within 2-3 mins. If yes, you are perhaps set to take the test.
