Hello Student,

No, It is not necessary  to attempt NEET exam next consecutive year if you are not prepare for it.This attempt in which you got fail  will not be counted as your 1st attempt.

You are given 3 attempts upto age of 25. If you fill up the form in 2018 then that will be counted as your first attempt. It means that how many times a candidate has appeared for the exam. If you are not appearing this year then you still have your 2 attempts left in you hand till age 25.

Hope it helps.

Thnak you :)
