It can be really challenging to manage both school and NEET preparation simultaneously. But once you learn to manage time, you can easily do both.

Since you're in class 11th, I really really advise you to complete your class 11th syllabus before starting 12th. Once you've got a good command in class 11th, preparing for NEET and boards simultaneously will be piece of cake for you. Complete class 11th before your class 12th starts and then complete class 12th syllabus by the end of 2026. Doing so will give you ample of time for revision. Focus entirely on NCERT along with taking help from several books available in the market.
