I would suggest you to go through the below tips -

1. Plan your studies - The first step which you need to do is plan your studies appropriately and this is only possible when you make proper schedule to complete your syllabus.

2. Sort out the important topics - Go through the syllabus and check all the lengthy topics and devote your maximum time in important topics only.

3. Comparison of your university and GPAT syllabus - Mark the common topics as the topics that are common need an increased attention as you prepare for your GPAT exam. Once you have finished creating a list of the common topics, start with your favorite topic. Choose a topic that is simpler than the others and immediately start studying it.

4. Read Books - As there are so many books available in the market so it is advsable to use the statndard books only which make all your concepts clear and strong.
