My daughter wants to become a doctor. Shall we switch from ICSE to CBSE will it be of any help. Please provide your opinion. Thanks is advance ?

I think there is no impact of you switch to CBSE,as medical includes biology as major portion and level of BIOLOGY IN ICSE is deep as in CBSE so if marks does not matter to you then you may switch but yes you might continue only ICSE biology so that your concepts remains great.

It's not necessary to switch board,just let her complete board without any confusion and prepare her basic concepts

ICSE syllabus is much  in depth than CBSE. After 10 th  class it really doesn't matter much . take good coaching for NEET exam preparation.
