i had compartment last year, and i cleared it this year. Am i eligible for IIT ,according to business rules one has to reappear in all the subjects. but in CBSE there is no such provision

If you have cleared your compartment, thenm there’s no issue at all you better prepare fpr the test properly and then try to seek admission. If you prepare so very well and eventually get a seat in a leading institution, well and good or else you may consider these institutions – CMR Technical Campus,,Hyderabad,..................J B Institute of Technology, Dehradun,...................Lovely Professional University, Phagwara
