Hey,

According to me you want to ask that how many times  you can appear for JEE Mains as well as JEE Advanced,

If yes then you can appear for JEE Mains as well as JEE Advanced three times from the year you gave your 12th examination in.

Hope it helps :)

Dear Aspirant,

You can give the JEE Mains only three times and so does the JEE advanced as you will appear to another after clearing one. And If in a year you have appeared two times then only one attempt is left for you. So I think this will solve your query. 

Good luck
