Hello dear student,

Btech is an graduation degree only but you can persue it if you have a combination of Physics, chemistry and mathematics in your class 12th . It's basically engineering. While graduation degree means it is degree for higher levels of education after an undergraduate degree Radha se you do graduation degree only after you pass your class 12th and after graduation degree if you are still interested in studying when you go for post graduation degree. Likewise there are degrees above this also.

Best wishes
