In 2020 NTA will conduct an exam for neet.

maybe there will be a two-exam which be held for neet like jee-mains 2019

if you have not done well in exam 1 than you can give another exam these all steps may be taken to reduce the peer pressure from student

In 2020, IF NTA will two conduct two exams than the first exam will be around December and the second exam will around May or June

BHU and AFMC are not going to conduct there own exam admission process will be through NEET score.

For admission either you go through AIQ or register separately for admission

so study hard you get a BHU and AFMC.

ALL THE BEST
