Hey, 

Take a Print out of the e-suvidha ticket and, choose particular colleges of your choice. Then, visit them and submit your Application form (which you filled online) and the e-suvidha ticket (XEROX OF BOTH, NOT THE ORIGINAL ONE). Then, you will be in the admission process.

I have a YouTube channel, and was working upon HSC Admission 2018-19 video and found your comment. Hope I helped you, if any doubt https://www.youtube.com/channel/UCP4ON0wTISeRetbqI7eIejw make sure you visit my channel and comment. I am reading each comment, and trying to solve every student's problems:)
