Hey,
Maths is a mandatory subject to pursue a career in Biotechnology. It is necessary to have knowledge of grad. level mathematics if you're going to pursue a degree in biotech. If you're in 12th standard and if it's possible that you can still add a subject in your current curriculum then go for it.
Mathematics is compulsory for admission in government colleges, only private colleges don't have maths as a compulsory subject. Since you'll be opting for a biotech course (most probably a B.Tech in biotech) then you will require the knowledge of mathematics (graduation level).

Hi Nikita,
You should not worry. There are many options available for you. You can take admission in IGNOU or Sikkim Manipal University for management courses in distance learning mode. They are best available in the country for distance degree courses. If you are interested in learning only, then you can register yourself for NPTEL courses. You will get certificate also from NPTEL after successful completion of the course.
Best of luck.

It depends on how the university processes international student's admission. Each university would have an intake period and you are applying for a particular intake. It would depend on how fast the university processes your application and your visa process gets cleared. It is better to contact the university directly, especially if the university has an international student's coordinator. They would be able to give you clear timeline.
