Hi adityanarayanan01,
Based on your description of how you have been studying, it’s quite possible that you have not fully learned all GMAT topics prior to taking your practice exams and thus are seeing inconsistent scores. So, prior to taking any more practice exams, you may consider adjusting your study routine to allow you to fully learn each GMAT topic.
When developing a new study routine, be sure that is allows for for linear and targeted learning and focused practice. In other words, you want to master one topic before you move to the next.
For example, if you are learning about Number Properties, you should learn everything possible about that topic: LCM, GCF, units digit patterns, divisibility, remainders, etc. After that, be sure that you practice with a lot of questions (50 or more) just on Number Properties. The results of that practice will help you to determine how well you have truly mastered that topic. You will want to follow this study routine for verbal (sentence correction, critical reasoning, and reading comprehension).
To allow for such focused learning and practice, you may consider using a self-study course rather than a book. In comparison to GMAT prep books, self-study courses typically provide detailed study plans and have granular analytics, so you can easily track your progress as you move through the course. By being able to track your progress, you will remain more engaged, and you’ll be able to forecast when you are ready to take your real GMAT.
Once you feel you have fully learned all the important GMAT topics, but not before, start taking Official MBA.com tests to track your progress. You can start with the

exam pack 1 and
exam pack 2. At this stage your practice test scores should be more consistent and more reflective of your GMAT score goal.
