Hello Somnath!

Are you talking about CS bifocal subject in 11-12th ?

To get into CSE it does not matter if you've had the subject before or not.

You can definitely think of the branch for your engineering as it's expanding every day and there's no limit of scope.

I myself am a computer engineering student, i never had the subject before. And it doesn't really matter. You may need to cover some basic programming concepts on your own. But you can do it easily with the course.

You'll have 4 years with you to master the subjects. If you're really interested in programming you'll see yourself doing everything you can to be 2 steps ahead if your peers.

So don't worry, if you're good in logical thinking and stuff, go for it!

Best if luck :)
