MBBS

Yes, it is worth doing only in Ukraine. don't expect a high package in India.

Go with BDS, which is same as MBBS.

I think it is not easy for you. You should be with your parents. Or you should made your parents with your side.

MBBS in Australia is higher. While the tuition fees for the medical degree in Australia remains considerable and vary moderately with every Australian university, the cost of living in this dream country counts to a minimum of INR. 15,000 a year.

Hello,
There is no specific course to study human reproduction but you can definitely study your interest online.

Low tuition fees (around Rs. 20 to 25 Lacs), affordable living costs (around Rs. 10 to 15 thousand), advanced technology, prominent faculty members, and easy process of MBBS admission in Ukraine are some of the prime reasons for Indian students to study MBBS in Ukraine. Also, you need not sit for any entrance test or qualify an English language test for getting into an MBBS course in Ukraine.

It is based on both 12th class marks and NEET score.

Yes, you can but you need to keep in mind that you need dedication for MBBS because there is very tough competition in that field. You can prepare by taking coaching too. It would be easier to go for BA or MS course, which has comparatively less competition, but if you can setup your own clinic then sky is the limit and you can earn more than in MBBS.

You chances of cracking medical entrance examination are definitely higher after B.Sc. You are advised to apply for medical entrance exams to fulfill your dream of becoming a doctor. However, if you do not make it to medical now, you may revisit your decision and opt for an alternate career option.

See, to be clear you can't manage both B.Sc and NEET together.
There is a saying that do not put each foot on different boats. So I suggest that do not mess up with 2 different courses. Just be clear about what is your goal, it is either B.Sc or getting MBBS through NEET. But remember one thing, you should be confident about what you want to choose. Your goal should be clear.
