Hello Kapil,

To get admission in colleges under HPCET through JEE Main score, you need to first fill the application form and register for counselling. Round 1 of the counselling will be conducted for JEE Main qualified candidates and 50% of the seats will be filled. Round 2 will be conducted for HPCET candidates and remaining 50% of the seats will be filled. Now to be JEE Main qualified , you have clear the required JEE Main cutoff as per your category. Below I have provided 2019 JEE Maim cutoff category wise - 

• CRL : 89.75
• GEN-EWS : 78.21
• OBC-NCL : 74.31
• SC : 54.01
• ST : 44.33
• PwD : 0.11

So if you have cleared the cutoff as per your category, then you are JEE Main qualified. Below I have provided the procedure for HPCET counselling : 

• Registration - Candidates have to first register for  HPCET 2019 by filling up the required details asked. After that they will receive a unique registration number.
• Filling of application form - After logging in to their accounts, the candidates needs to fill up form with their personal,academic and contact details.
