Hello,

I would suggest you to join CBSE board as NEET is a national level entrance examination for the admission to all the reputed Institutes all over India.

In addition to these CBSE follows NCERT syllabus which is also followed by the NEET examination. Sometimes direct questions comes from NCERT textbooks. So you would have an edge as compared to icse or non cbse boards .

And in addition to this also opt for coaching for sure because they would teach you about the level of the questions and the importance of the NEET examination. There will be mock tests conducted by the coaching which will make you comfortable with time management and accuracy.
