Hey,
Your doubt is not clear to me. But your profile says you are engineering aspirant. So i am assuming that you are asking about JEE Mains.
In 2021, NTA has increased the number of attempts. Candidates can appear in the exam for four times in a year.
Apart from this, in general, candidate is allowed to appear in JEE Main for three consecutive years from the year of passing his/her class 12 board exam.

Apart from Jee Mains, there are various entrance exams and state counselling which are gateways for various engineering colleges such as BITSAT, MHT-CET and so on.
Hope that helps.
