Please clarify, what do you mean by common classes. 

I am assuming that you are referring to Lectures for Class 11 and 12, if not please specify.

Yes, this year our main focus is JEE and NEET.

But this does not mean that there is not enough resources to study for boards on our platform.

You can always refer to one shot videos of all chapters made by Roshni ma'am. They are great lectures to clear all your concepts.

Then you can also refer to NCERT solutions of every chapter.

If you still have doubts, then you can come to doubt sessions of each and every chapter, which is mainly conducted for JEE and NEET. But you can also ask questions of Board level.
