Hello Hari Om,
As you are a biology student and if you have PCB in class 12th, then it will be difficult for you to get admission in engineering. I would suggest you to take mathematics as an optional subject if possible because after that many options will be open for you in the field of computers like CS or IT engineering, BCA etc.
At this time, you can only go for 1 year Diploma course in computers like hardware networking, web designing, etc.
