Diploma

Yes, you can. You just need to appear for the entrance exam.

Dear Sanjoo , maximum of the animation institutes in INDIA normally does not look for any particular cutoff marks , If you have cleared your 10th , you must be eligible to join a diploma in animation course .

It is suggested that you complete your diploma and seek lateral entry in branch of your choice in second year of engineering. You can try Anna University for lateral entry into Automobile Engineering.

With this score, getting admission in Indias good universities will be difficult. Canada diploma will suit you. Many colleges in Canada offer diploma programs however a degree holder has more value. I will suggest you to enroll for diploma but later opt for degree courses. Usually students don't return to India but in case you want to don't go for diploma courses. A degree from reputed university works better in India as well

Degree courses always have more value as compared to diploma. But as you are already applying for degree so doing diploma will not decrease the scope for better jobs.

Dear Mahesh, US is very competitive but if you manage to get through one of the top universities you can consider yourself lucky. In terms of work permit Australia is easier though compared to UK and US. Check the pros and cons, expenses, post study work permit schemes etc before deciding where to study.
