I got 232 as preparatory sc rank. will I have any chance to get into iit bombay in further 4th or 5th round

With an SC Preparatory Rank of 232, getting IIT Bombay is possible but highly uncertain. Admission through the preparatory rank list depends on the availability of vacant SC reserved seats after the regular JoSAA counselling rounds. There is no guarantee of allotment in the 4th or 5th round. Continue participating in all counselling rounds and keep a wide range of IIT choices to maximize your chances. Preparatory course seats are allotted only if reserved seats remain vacant.

Thanks and all the best,
