Hello there,

You can always prepare for any entrance examinations while you are in college. It may be GATE,UPSC,CAT,XAT etc.

UPSC and GATE are one of the most toughest examinations to crack in the country. Also the percentage of people qualifying in it is also very less.

Therefore,it is advised to you that you should always focus on one of the entrance examination you wish to suceed. Preparing for both may hamper your studies in your college as well as for the examination you are preparing for. At the end, it may not be beneficial for you.
