i want to know which board is the best ICSE ,CBSE, CHSE for +2 studies i need ur help expert plzzz help me

If you're an ICSE student, ISC is the best for you. You can go for CBSE or CHSE if you want, but it's best if you choose between ISC and CBSE.

If you're a CBSE student, CBSE is the best for you.
If you're an HSC student, CHSE is the best for you.

If you want to study engineering, you can go for any of the three boards.

If you want to study medical or one of the basic sciences, go for either CBSE or ISC.

Note: CISCE(ISC) has a much better English syllabus than other boards.
 

I'm not an expert, though.
