how COME book is useful for 12th TN stateboard syllabus?

Hello,

which book your are asking about. There will be a prescribed book for your +2 1st and 2nd year. Those will only be helpful if you appear the state board. This has the same syllabus to NCERT but concepts are bit more and bit lengthy too.

It will be useful during your entrance time as you can refer them too along with NCERT. The main thing is if you consider any exam it has some prescribed books. And mostly syllabus is same. It okay to use own state board books along with the prescribed books also.

You will any way will study the same concept only. If you have any more queries then feel free to ask.

Hope it helps!
