Hi sav23,
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 scores can vary a bit based on the 'biases' involved in their respective designs. While the most realistic CATs available are the 6 from GMAC, 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). In addition, by doing anything else that is unrealistic (such as pausing the Exams), then it sounds as though at least a few of your CAT/mock results are unrealistic. 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) - so you can use any NEW CATs from any of those sources next.
It's also worth noting that the process of taking (and reviewing) a CAT requires a significant amount of energy and effort - and takes time to 'recover' from. This is one of the reasons why you typically shouldn't take more than 1 CAT per week - and your last CAT should be taken about 1 week before Test Day. If you are planning to take the GMAT on June 9th (in approximately 1 week), you might be okay taking one more CAT, but you should NOT take any more than that.
Many GMATers face pacing issues in the Quant section, the Verbal section or both – so you are not alone. However, it's important to remember that pacing problems do NOT exist on their own - they're the results of OTHER problems. Based on everything that you have described about your pacing issues and uncertainly about your actual 'ability level', you might want to consider pushing back your Test Date.
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? Have you taken any other CATs/mocks than the 7 that you listed?
Goals:
3) What is your overall goal score?
4) When are you planning to apply to Business School and what Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
