Hi abdelazizlila,
It's not clear what type of 'test' you're referring to, but I don't think that it's one of the Official GMAC CATs. As such, it would be a good idea to take a FULL-LENGTH practice CAT Test; you can download 2 for free from
www.mba.com (and they come with some additional practice materials). That score will give us a good sense of your natural strengths and weaknesses and will help provide a basis for comparison as you continue to study. A FULL CAT takes about 4 hours to complete, so make sure that you've set aside enough time to take it in one sitting. Once you have those scores, you should report back here and we can come up with a study plan.
Earlier this week, GMAC made a formal announcement defining some changes that will be taking place to the format of the Official GMAT (beginning April 16, 2018). These changes primarily impact the overall length of the Exam (meaning the number of questions in the Quant and Verbal sections as well as the amount of time that you’ll have to complete each of those two sections). In theory, a shorter Exam could make it easier for a well-prepared Test Taker to score higher. Unfortunately, practice CATs in the new 'format' don't exist yet - but once they become available, you should also plan to take one (so that we can get a better sense of how you perform under these new conditions).
Before I can offer you the specific advice that you’re looking for, 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?
2) What study materials have you used so far?
Goals:
3) What is your goal score?
4) When are you planning to take the GMAT?
5) When are you planning to apply to Business School?
6) What Schools are you planning to apply to?
