Hi,

At this time the admission to gb pant university are taken through CAT and CMAT score and Group Discussion and an Interview conducted by the University.

To prepare for the entrance exam check the syllabus of the exam. Make a time table considering your time management. Practice the previous Yeats question papers. Join mock test or some good coaching if you can afford. You can pass these entrance exam by doing self study too.

For CAT exam for quantitative aptitude ,logical reasoning and data interpretation you can refer arun sharma, nishant k. Sinha etc.

For the topics like logical reasoning , verbal reasoning, comprehension, quantitative aptitude you can refer any good book which you. Like instead of buying much study material buy 2-3 books for each section of syllabus in entrance test and study and revise it timely.Frame a  group of 3-4 friends to practice group discussion.

As you have two years to complete graduation you can easily prepare in this time for entrance exams of CMAT and CAT.

Hope this helps.
