NCERT

Hi. Teaching courses after 12th Certificate Courses are-
Certificate in Elementary Teacher Education (CETE)
Certificate in Primary Education (CPE)
Certificate in Guidance (CIG)
Certificate in Primary Curriculum and Instruction (CPC)
Certificate in Primary Teaching (CPT)
Certificate in Basic training (BTC). .

I had similar kind of questions when I was in your class. Class 11th is way much important than we think, you'll need every sentence you've read in class 11th later
You should stick with NCERT books and keep solving exercise, intext and additional exercise questions too. You'll find same exact questions in previous year papers. You may download it online.

If your preparation is good and of high level then no problem if you skip it.
