I took pcmc in 12th which course I should do in bsc
Hii Pavan
It all depends on your keen interest that in which field you wanna see yourself in future.
If you think you are good at programming language and it's other skills go for computer science. Is you feel that you are more connected with the imagination of electrons go for physics or or your connection with chemicals will tilt you towards chemistry.so choose wisely the subject of your preference only.
Feel free to ask any other query!!
