Hi.

If you have not qualified the JEE Advance that means you have not been allotted any seat in any of the IITs which means that you cannot take part in preparatory course. If you have got 0 marks in one subject, but your minimum marks aggregate is 10 marks then your name may be listed in the Preparatory Course rank list.

Because, these courses are organized for students belonging to the SC, ST, PwD Categories who have been allotted a seat and intends them to prepare for the course.

Good Luck
