How and when can I apply for engineering colleges accepting jee and mht cet? Plz tell me about the detailed admission procedure.

Procedure to get admission in an engineering college through JEE mains:-

1. NTA declares JEE main score and asks top 2,24,000 students to apply for JEE Advance.
2. As soon as JEE main results are out, all the colleges that accepts JEE main rank, open their counselling portal for the admission in B.Tech.
3. Students apply for the counselling in different Universities/Institutes by paying the counselling fee.
4. Students give the preferences of the Branch and Institute in which they want admission.
5. As soon as counselling results are out and students who are allotted seats are asked to pay the admission fee by visiting the institute they've been allotted.
   Usually there are 3-4 counselling rounds and a spot round in which counselling is based on physical appearance of the students at the institute in which they want admission. Spot round may also be an online round in which the University/Institute asks the students to pay the fee in advance and if they're not allotted any seat, then 100% fee will be refunded(Not the counselling fee but admission fee) and if you're allotted seat then you can't withdraw yourself.(You should read the instructions carefully before applying for the counselling.
6. And then comes the first day of the college

For CET, The allotment of seats will be done on the basis of merit list released and choices filled by candidates. The State Common Entrance Test Cell, Maharashtra will conduct MHT CET 2019 seat allotment through a Centralized Allotment Process (CAP) in online mode in three rounds.
