Hello Lahari

hope you are doing well and safe. With reference to your query,  I would like to say this query is not clear and can be answered only by assumption . If you are asking the college year  , yes have to repeat the your current year again if you take admission in any new college and you are dropping for jee . Admission are given only in new session you cannot take admission in the middle of the year. Study hard for jee and crack top nits and iits

Hope you found this answer informative. Best wishes for your future
