Hey there!

The answer to your question depends on your score in the examinations for the respective colleges. If you achieve the cutoff then you'll get a seat, you can refer to previous years cutoffs to see what your score should be on an average. For admission in JIPMER and CMC you'll have to appear for the NEET examination. For admission in AIIMS you'll have to appear for the NEET examination only from this year. If you have appeared for the NEET examination and wish to know your chances in these colleges check out the careers360 college predictor to help you with that. I'll be attaching the link below
