I am a science student in 10+2 and now I want to do B.A .
Hello Tek,
It's totally fine if you want to do B.A after science.It's totally acceptable and possible too.In fact 2 out of 10 students in B.A are science student.Just see to it that you get high marks in your 12 science as arts cutoff are generally higher than bsc.Also every college and university accepts science students in arts.
Hope it helps.
