Hello student. You can write the exams without attending the college regularly. But there are two things here. Firstly attendance, find out if your college has cut off attendance which has to be maintained strictly. If that's the case, then you have to attend the college to maintain that. As in, if they specify like 80 percent of attendance is compulsory, then you need to have an eye.

Second thing, if there is no such attendance criteria, then you can self prepare. But think that how far is it useful. Will you be able to pull it off without classes. Think and take a step
