Give competition exams like JEE, BITS, VITEEE, COMEDK, WBJEE, etc. and grab a seat in the best engineering colleges of India.

Yes, you can apply.And there is no pattern you should fill the form again for the exam . You just have to do one thing that is while filling the form you should mark the column of reappearing.

It is not mandatory to apply for a course in B.Sc before you have cleared your class 12th exams.
The minimum academic eligibility criteria for B.Sc course is that the student should have cleared their class 12th with more than 55% marks to apply for the programme, so it is advisable that you apply for the course after you have cleared your class 12th exams. Regards.

It depends on your CAT score. If your percentile is above 99, however, you need to be in the graduation final year without any backlog in order to be eligible for appearing in CAT.

Hi Lance Hood, If you are an exceptionally bright student then even the top 10 universities will accept you. But the issue is you haven't mentioned anything about your academic background and extracurricular details so can't comment anything further. You may check the top university websites and match the requirements with your own profile. You will have an idea of the areas you need to improve on if any.

Hi Cherish, chances are good but nobody outside the university can tell you if you will get it or not. It depends on the university, other applicants, they will see how competitive you are with the rest, if you meet all criteria you can. You must also have a very good all-rounder profile, a strong personal statement and good LORs. Apply early, don't wait till the last date of the deadline, it will hamper your chances. And check the university website carefully for scholarship and financial aid options and requirements.
