hlwo aspirant

hope you are doing well

see your ranks depends on many factors with 50 marks like reservation etc

but If you get 50 marks in Jee Main, your rank will be around 2,50,000

you cannot get admission in IITs/NITs/IIITs or in any government college with 50% aggregate in qualifying exam.To be eligible to get admission in IIT/NITs/IIITs a candidate must have passed 10+2 or its equivalent with Mathematics, Physics and Chemistry. Candidates belonging to general categroy must have passed with atleast 75% aggregate and for SC/ST it is 65% aggregate.

hope this is helpful for you

best of luck
