Hi adityanarayanan01,
Since you are about a month away from your GMAT, you may consider taking one test each week to track your progress. At this stage you want to affirm that no “rust” has accumulated on the topics that you have studied. I am not certain whether you have exhausted the official practice exams, but if not, I find that those exams most closely represent what you will see on the real GMAT. Currently, there are 6 total practice exams offered by GMAC:
two free exams,
exam pack 1 and
exam pack 2. As mentioned above, taking practice exams is a great way to track your progress. After finishing each exam, spend some time reviewing your wrong answers. Do some deep analysis of why your responses were incorrect, reviewing, if necessary, your notes concerning your weakest topics.
When taking your practice exams try to replicate the test day experience as much as possible. Take your exam in a quiet location, preferably at the same time and day that you will take the scheduled exam. For example, if your GMAT is scheduled for 11am on a Saturday morning, take your practice exams at 11am on Saturdays so that by the time your test rolls around, you will be mentally prepared for an exam given then.
One last point to consider. If you find that, on your practice exams, you are not scoring within your desired score range, you may want to give yourself more time to prep for your upcoming GMAT.
