Parimala, you have a good percentage of marks, better than many others. But for your information, your percentage in boards doesn't matter when you want to get into an engineering college, your J.E.E. rank (national or state-level entrance, which ever you appear for) is what matters.
With your choice of words, it feels that you have made up your mind to study engineering but you're confused about which stream to get into.
C.S.E. is a flourishing field and present broad opportunities, both career-wise as well as for higher-studies.
If you are a geek who likes to spend hours on your desktop developing apps or websites or coding algorithms to provide solutions to complex problems, C.S.E. is the stream for you. However, you also need to make sure you have mathematics and a little of electronics in your arena of interest.
Also, if you have a biology background , do not be scared. If you're dedicated and passionate enough about C.S.E., there's no one who can stand in your way to success. Focus on yourself and do not be demotivated by your fellow would-be classmates if they be better at coding than you. You'll learn everything on the way once you start.
Best of luck!
