Mai is samay Bsc 2nd me hu.kya ab btech bhi saath me kar sakta hu
Okay, so basically you are pursuing B.Sc course in 2nd year.
You can not take 2 courses simultaneoulsy as it's not allowed by rules of government.
But you have option of pursue B.Tech course after completing B.Sc course through lateral entry scheme offered by most colleges of India.
You should graduate with more than 55% marks in science stream of B.Sc and have took maths as compulsory subject.
