What GMAT prep test is the most accurate score indicator?

Probably fair to say the best mocks are the Official Mocks.

Hi laen3099,

The official mocks are the most reliable ones as it is believed to be the closest to the actual GMAT exam.

All the very best for your GMAT! Do share your test day experience.

Hi laen3099,

The scoring algorithm on the Official GMAT is far more complicated than most people realize. Since that algorithm is proprietary, no GMAT company has an exact match for it, thus CAT/mock scores can vary a bit based on the 'biases' involved in their respective designs. The most realistic CATs available are the 6 from GMAC, but retaking a CAT that you've already taken is NOT a realistic way to assess your skills - since you will likely see some 'repeat' questions that you have already faced. Unfortunately, seeing even a couple of repeats can 'throw off' the Scoring Algorithm and impact your pacing, energy levels, fatigue, etc. (meaning that they would likely all appear to be better than they actually are). Thankfully, the CATs from Kaplan, MGMAT and Veritas are all 'close enough' to the real thing that they will provide you with a relatively realistic score assessment (assuming that you correctly take the CAT in a realistic fashion that matches the parameters that you will face when you take the Official GMAT).

It's also worth noting that there are a variety of factors that can impact your performance on a CAT, including the type of Exam that you're using, the time of day that you start the Exam, the testing conditions, how well-rested you are, the section-order, etc. Based on the information that you have provided so far, it's likely that you are a strong overall critical-thinker - so a good question to ask yourself when reviewing any of your CATs/mocks is "how many questions did I get wrong that I could (or should) have gotten correct?"

Before I can offer you any additional advice for your studies, it would help if you could provide a bit more information on how you've been studying and your goals:

Studies:
1) How long have you studied? How many hours do you typically study each week?
2) What study materials have you used so far? What “brands” of CATs/mocks have you used?
3) On what dates (or approximate dates) did you take EACH of your CATs/mocks and how did you score on EACH (including the Quant and Verbal Scaled Scores for EACH)?

Goals:
4) What is your overall goal score?
5) When are you planning to apply to Business School and what Schools are you planning to apply to?

Hi laen3099,

As has been said, the official practice tests are the most accurate. Do you plan to take any other official practice tests prior to your exam this Friday?
