Hi Rhy1399,
To score at a high level on the GMAT, you have to have a variety of skills (more than just content knowledge) and the only way to properly assess whether you have those skills or not is to take FULL-LENGTH CATs under realistic conditions AND at regular intervals. If you have any built-in 'bad habits' when it comes to taking a Test, we need to know about those issues sooner rather than later (so that we have more time to 'fix' them).
If you've been studying for 4 months, then you really MUST take a FULL-LENGTH CAT (including the Essay and IR sections) sometime soon (perhaps this weekend). That initial diagnostic CAT is important - it helps to define your current strengths and weaknesses and gives you a basis for comparison as you continue to study. Most Test Takers are not happy with that first CAT result, but that's not a big deal - the extra months of available study time are there so that you can IMPROVE on this initial practice result. You can access 2 CATs for free at
www.mba.com. Once you have your Score, you should post back here and we can discuss the results and how you might best proceed with your studies.
In addition, it would help if you could provide a bit more information on how you've been studying and your goals:
1) How many hours do you typically study each week?
2) What is your overall goal score?
3) When are you planning to apply to Business School and what Schools are you planning to apply to?
