Select single group or both group?

I will suggest you to give both the groups as you have more than one year which is enough for CA final

Best of luck for th exams

But how I manage self studies with classes n office

That's what is CA.. We have do the effective time management.

You have to plan your day and schedule accordingly so that you give proper time to your studies.

Ok I will try.thanks...

But I think its very hectic schedule if I will  do both group.
