Best of luck.

I think, you must go for full-fledged animation course because animation is very vast field. In full-fledged course, you have graphic designing, web designing, 2D animation, sketching, 3D modelling and 3D animation.
These courses generally last from 2-3 years. But, I personally prefer you to go for full-fledged course.
All the best.

B.Sc (Hons.) physics followed by M.Sc-Ph.D is the normal path of education for you based on your interests.

Prepare the basics well for IIT-JEE and keep trying the application based questions from reference books. Basics will help you to tackle board examinations. Practice previous year's board exam papers to get an idea about the exams.

You have very strong chances of receiving a call since last year's CAT cut-off for PGDM and PGDM-IB was 84% and 76%.

40% unfortunately is too low for any foreign university, let alone Canada. Please understand that you must qualify to pursue higher education and certain norms must be met. The only possible way is to pursue your Bachelor's or diploma India and perform well academically before applying abroad.

Tips for preparation :
Start reading your NCERT book as soon as possible. Follow up your NCERT concepts with a reference book to gain a deeper understanding of the topic. Do not ignore numerical problems. Most of the times, the problems are direct application of the formulae in use, and, at times are mixed with your understanding of a topic. The numerical problems, if mastered are a good way to score marks. After you finish your syllabus, revise as many times as possible.
