HI NAVYA hope you  r doing good i understand u r problem

1. see navya that depends on particular state,considering you r from telugu states i think it is not possible to continue your second year with bipc ,rejoing is the only option for you (if you wish (strongly)study medicine )

2.but in tamilnadu it is possible ,i think so, you please ask your principal they may provide complae info to you

NOTE : 1 some of my friends(who is studying final year medicine ) said it is not possible if he /she completes the first year
and it is possible with in five months after joining first year..

NOTE : 2 BEFORE TAKING DECISION SHARE YOUR THOUGHTS TO UR PARENTS

***   ALL THE BEST ***
