Thanks for the question .

Candidate is required to register through REAP-2018 web portal. Candidate may register on the basis of

JEE Main-2018(Paper 1) rank or Class-12 marks/percentile. However, the candidates are advised to

register on the basis of JEE Main-2018(Paper 1) rank as JEE Main-2018(Paper 1) rank would be given

higher priority in comparison to class-12 marks/percentile in preparing the combined merit list

during all the stages of counseling in REAP-2018.

S.No Basis Priority

1 JEE Main-2018(Paper 1) rank 1

st Priority

2 Class 12th Science Marks/ Percentile. 2

nd Priority

So, register yourself first and wait for the counselling call. 

All the best
