Doctor

Hi Akshatha,
Sure you can, you only need to clear the country-specific medical council licensing exam which supposedly is very tough and rigorous. You can check on the internet for more information depending on which country you want to serve.

Yes, but you need to have biology as an optional subject in Class 12th to pursue B.Sc and then go for Ph.D.

Hello Vivek,
Firstly, think before you do this because you've done engineering already and now you want to switch your career; That's a tough and life changing decision. If you really want to become a doctor you have to appear in NEET, MHCET, AIMS, AFMC, etc. exams. You also have to score good in those exams so that you can achieve a good AIR for yourself. I suggest you must discuss this with your parents, senior friends and teachers before jumping on any conclusions.
Good luck.
Thank you.

Find a suitable location.
Apply for a drug license.
And, while applying you have to submit one pharmacy certificate (it is not necessary, that it should be yours or the person you are hiring)
Usually, pharmacist gives their certificate for yearly basis and amount varies.
If at all, you clear that inspection then they will give you certificate to sell drugs.

Hi Shivam,
Since you are a Biology Student, interested in Biological Science.
My recommendations to you is to choose among:
1. Biotechnologist,
2. Microbiologist
3. Zoologist,
4. Agriculturist,
5. Forestry

What is your score in 12th?

Both the fields have their own importance. One cannot decide which field is better, unless you decide.
First preference is your interest area. Then later comes the pay scale. See, if you want to your salary to be good, then choose B.Pharmacy rather than BAMS Doctor.
If I was in your place I would have chosen BAMS Doctor. The behind reason is that I know this field better and I'm interested in it too.

Hi,
She must take the SAT or ACT and apply for a Bachelor's degree programme in biological science, thereafter she must clear the Medical College Admissions Test (MCAT) to seek admission in a medical school. There is no MBBS like in India.

I would suggest that you take up medicine as your primary filed and acting as secondary. And if you do this as suggested and further think of joining acting then you can take up that as your first preference and probably then your parents will also support you.
