Hi Alok, i am afraid that there is no other go but to crack NEET if you have to get admission into medical colleges, but there are few other options,

1. you can try to crack AIIMS if you are strong with physics and chemistry as its of equal weightage whereas in NEET biology is predominant and AIIMS doesnt require NEET

2. the same as above applies for JIPMER and if you are good at english and if you have pondicherry quota, it makes your life easy then

3. go abroad and do your mbbs in countries like Russia, china, which is easier to get, good luck buddy
