can i appear in jee advance 2021 if I pass out my 12th in 2019

Hello student I'm sorry to inform you but you're not eligible to appear for jee advance in 2021 as eligibility criteria says that Candidates are only eligible to attend Jee advance in two consecutive years one in the year of passing board and another in next year. However you're eligible to appear in Jee main 2021.

Application form for jee main April examination starts from 07th of February and shall remain open till 07th of March 2020.

Feel free to comment if you have any doubt
Good luck
