I've heard from somewhere that if I get a rank in JEE under 50000 then I would not have to pay tuition fee in Chandigarh University. Comment

Hello Candidate,
There are several private institutions which provides relaxation of tution fees for good rank holders.
To know more visit the university admission portal .
My suggestion for you is firstly prepare well for April Jee than after April Jee you can visit many institutions which provides exemption from tution fee.

If you have any questions remain than comment below.
Good luck...
