Hello
Schooling and non - schooling both have their Own benefits and loss. It's totally depend upon student whether he want  to be a regular schooling or non schooling candidate.

Regular schooling means you will attend your schoolon a daily basis.

Non -schooling candidates are those who appear only for exam they don't have to go school daily.

Benefits of regular students
1. Better understanding of board syllabus.
2. School environment
3. Get various opportunities for interactions
4. You can make good friends.
5.live interaction with school teachers.
6. Lifetime memories .

Loss-
1. Less time for preparation

Non- schooling benefits
1. You can dedicate your 10- 12 hours on your neet/ jee exam .


But i believe it's totally on students the only deciding factor is time of preparation for which students join non schooling.

Hope this will help

Best of luck.
