sir my preparatory rank in sc is 2983 can i get admission in iit?
Yes I believe having a SC Rank of 2983 will ensure admission in Preparatory Courses in IIT. Preparatory Courses are conducted by the top 7 IITs and will be a good experience for you before you finally enter the Btech/Dual Degree course at some IIT.
