Is preparatory course better in iit ? As i got preparatory course in 2019-2020, as I can start 2nd year btech

Preparatory courses are offered when the seats are no filled owing to a minimum criteria set for filling the seats inorder to filmthem IITS offer preparatory course that include teaching of basics i.e. you would be repeating 11&12 and after that a screening will be done and after you clear the screening you will be allowed to continue your BTech with the rest of the batch . Else you will be terminated. So see to it that you do study there at IIT and are not in some dream that now you are studying at IIT else you will have to face repurcussions.So you see for yourself here if ou are determined enough you must join the preparatory courses.
