Should I take admission this year or wait for the next year? I got to know that the classes have started I want to take admission.

Yes clases have been started but u can join this year also as colg provide with back up clases and i even heard that new batch is about to start .

Classes are started from 1 st August so if u r able to cover the syllabus it will be ok to take an admission but provided that college have to allow it, u can contact to college and because if is not feasible to waste entire year.
