Class 12-science

Hi Vaishali. You didn't mention the particular name of college. In that case, I won't be able to give the proper answer. But, as per your question, I'm providing some information. The basic criterion of eligibility needed to be met for admission to the course is a Higher Secondary (10+2) or equivalent qualification from a recognised educational Board, with Physics, Chemistry and Biology and/ or Math as main subjects and a minimum aggregate score of 55%. However, a few private universities in India conduct their own entrance tests for evaluating and admitting students to the course.

Yes, you can get admission in this course.

Hi,
If you want to take JEE then you need 75% marks in 12th (PCM).

As you are interested in computer science field you should either go for B.Tech CSE or for BCA which have wide scope. Computer science engineering is the most demanded in modern era.

If you have completed your class 12th Science, then there is no procedure to change your subject to commerce. You can directly pursue BBA B.Com (Hons) or any such type of Commerce field.

See, first, do complete your graduation with B.Tech in any field you are interested in. After that, you have to appear for the entrance exams GRE or TOEFL, or IELTS for foreign universities. According to the score in these exams, you can get the admission in aboard for MS course. You can also get scholarship if you scores good. Your B.Tech results will also impact to get admission abroad. Hope this helps you.
Thanks.

See, you should not go for the diploma or engineering because you have less marks in 12th which will impact bad on your placements. Because almost all companies allow only those students to sit in interview who had minimum 55% marks in 10th and 12th both.
So, you should try for other course.
Thanks

No, only students who had PCB in 12th class can go for GNM course. You are not eligible for that.
You should go for other courses like B.Tech, B.Sc, B.C.A, B.Des, etc.
Thanks

You should go for BCA or B.Tech with any field in which you are most interested. As you had CS, then you should go for B tech with computer Science branch which is 4 years course. BCA is 3 years degree.
Thanks.

You should go for B.Tech or BCA course and you can select the field in which you are interested like Mobile technology. You can do your B.Tech in same field. Thanks.
