Hello Shrawan,

NTA has changed the pattern of attempts from two to four in a year, so that students get a chance to improve their results. It is clearly mentioned in information brochure that it's not compulsory to appear in all four sessions. You may attempt any of them you want. It's all up to you.
You may predict your rank and percentile through:

Thank you!
