Hello aspirant,

There are some eligibility criteria that you need to fulfill to appear for jee mains which is given below:

Only those candidates who have passed the Class 12/equivalent examination in 2020, 2021, or those who are appearing in Class 12/equivalent examination in 2022, are eligible to appear in JEE (Main) – 2022.4 irrespective of thier age. Also the 75% criteria has been removed for this year in Jee. So if you have passed your jee in the above mentioned years then you are eligible for the jee exam otherwise not. So no diploma works for jee eligibility. Hipe this helps

Thank You!
