‘Dropper’ seems like an odd term to define someone.
I did have a roommate during my first year of MBBS at JIPMER who took a year drop after her 12th. During this time, she prepared well for her medical entrances. After a year, she cracked the JIPMER exam with an under 10 UR rank. After her college graduation, she went for her MS OBGY at AIIMS Delhi.
With hardwork and dedication, you’ll surely succeed in getting into JIPMER for your medical studies.
