Dear student

As per my knowledge , you can opt for mbbs after completing bams. But, you will have to go through it from starting, ie., you will have to give neet exam again , score well as per the cut-off of the state where you want to get the college and then go through all the councelling rounds again. You will have to start afresh. I don't think that's a better option. And you will also have to check your age, because for giving neet, you should not be above 25 years of age. After BAMS you can go for higher studies like MS , MD or dona short term course like physiology, ENT, forensic etc., At last it depends on your choice , if you are eligible and can go through all of it again,  go for it. According to me, that's not a good option. BAMS is also a good field and you get so many further options of employment in it too. Whatever you do, be happy in doing it.

All the best.
