You definitely cannot change your past now. But if you study diligently for the next few months you can surely change your future with a degree from a reputed college.

All the best!

Hi Ahutosh, the marks for graduation, 12th and 10th does not decide your percentile in CAT but hold weightage when colleges select candidates. Instead of worrying, it is better to join a coaching institute and take as many mocks as you can. The institute will teach you about all the topics that are asked in CAT but you also need to to self-study along with coaching classes. If you practice well, you can get a good percentile. Also, the classes help you to develop speed and learn tricks and techniques to crack CAT. It is always advisable to look for an insitute rather than preparing yourself.

Good Luck! 

dear ashutosh yadav
