Hey aspirant,

As far as I know and will advice you that you should opt only that career option in which you are comfortable and interested. As of course you won't like to waste your precious time in studying something in which you are not interested. And also even salary is inter connected with your interest. It's but obvious that if you are interested in something then you would give your best in it and can do a lot better whereas if you are not interested in your subject then you would just study for the sake of a degree but that won't help you in professional life so ya, that's totally upon you.

Now, coming to your second question, as per the information , bams is in either english Or sanskrit medium. It varies from universities to universities.

Hope it helps.

Good luck.
