CBSE

Hi Aniket,
You are good at maths, but still failed. Quite surprising and no, without a strong mathematical background, you cannot possibly study what you want. You should consider retaking the exam and improve your scores significantly to be accepted by universities abroad. If you are really into astronomy I will suggest you take online courses a MOOC. This may help to further advance your studies.

If you have got very good marks in all other subjects, then grace marks up-to 8 is can be given to the student not more than that.

Interested candidates can apply directly to the college. Basic eligibility to pursue this course is that Candidate must have passed 10+2 from any recognized board. Regards.

BCA will be a better option if you are interested to make your career in IT industry.

The scholarship is granted on the basis of 12th overall performance. There is a slab system and a student securing above 80 % marks overall is eligible for scholarship in 1st year. The continuation of scholarship for subsequent years solely depends upon his/her annual performance and conduct.

Hi,
Yes with 80%, you have a good chance. Please check the department specific entry requirement, some may require entrance test in addition to board exams. You can check this:
