Hello Shiya

If you're planning to simply buy a degree (getting private education) I would say take a loan or something and do only MBBS or nothing. BDS and BAMS are both nice prosperous fields but not worth private education. However if you're looking for a government seat, here is how you can rationalize your decision :

There are a lot of aspects in which BAMS Is better than BDS, and also vice versa .

For Bds you will have to invest 15-20 lakh for your Graduation(Private) then 20 more for your clinic.
