Degree

Yes, you can take admission in Bachelors degree after 12th.

Hello Akash,
Some universities do accept engineering as the eligibility for admission to M.Sc courses. If your intended institute is accepting it then you can go ahead. But I would advise you to go for executive MBA of one year in one of the IIMs.

Yes, you can because you are a graduate now.

Do you mean that you will study in India and look for a job in the US or study any of these in the US and work there? Whatever you mean, my recommendation goes for an MBA from a reputed university if you are interested in Business. If not, then first find out what you wish to do and go for it. All streams/courses have ample scope in the US or India.

Please refer to the link provided below for a list of colleges which offer distance courses in medical from India. Additionally, you can download their brochures which contains important information regarding course eligibility, admission dates, application form availability, etc.

Hi Karandeep,
You have a PG already so you may not be accepted for another Master's course in Canada. You have to make a better plan and also check out other country options.

You should consult with your admission authorities whether they will let you sit for your backlogs. Once you have cleared your backlogs you can join your job without fear of backlash from your organization.

Hello Baljeet,
Yes, absolutely. They accept three year's Bachelor's degree. All European countries do.
