B.Sc

Hi,
As you have not mentioned the name of the college so the fee structure will be as per the college reputation.
Generally, the fee structure is between 1-2 lakh per year for engineering.
As per the admission procedure of all colleges there will be an entrance test for admission which will ask you the questions related to 12th (science).

Yes, with your subjects, you are eligible for B.Sc in computer science.
All the best for your future.

It is a great rank. I think you can get admission.

Nice planning about the future, it's better to ask your faculty members for the better information because your faculty knows at least some little things about you so. It's better to ask them.

Dear,
I believe that no student is bad or average. It is the failure of the teachers concerned who failed to motivate a student and making him really interested. If you can motivate yourself internally and aspire to have an in-depth knowledge of physics and have a dream to go ahead with Physics. I think you can pursue Physics inatUG level. Your success in Physics awaits.
All the best.

BAMS would be better. Nursing is a hectic profession. By doing BAMS you will at least save your respect, unlike nursing. And nurses are not paid well in the private sector as compared to doctors. Unless you crack any staff nurse exam that also it's a hard luck because there are less vacancies as compared to number of candidates.

In Open university.
