CBSE 12th

Hello, yes with your 12th boards marks you can easily get admission in SXC for B.Sc honors in physics. the course is of 3 years and the basic eligibility criteria is "Passed 10+2 with an aggregate of 60% with pass marks in English and 60% in Physics".
All the UG courses are offered for a duration of three years. The application procedure for all these UG courses usually commences in the month of May every year. Students who have finished their 10+2 can apply for the undergraduate courses provided they meet the eligibility criteria.
Selection is done on the merit basis of marks obtained in qualifying exams for all the courses.

You need to not produce marks sheet, you can just mention that you are appearing for 12th exams this year. The options are already mentioned in the online forms you need not worry just fill the application form when it's out.

As for my perspective, you should go for B.Sc or B.Tech in private college, because your class 12th percentage are not good.
