Hi Staish,
The process is through an entrance test. You must score at least 50% to be eligible. Interview and medical tests are also to be cleared before you are selected, but it will vary from institute to institute. Ideally, you need to complete a Bachelor's degree in nautical science or marine engineering to become a merchant navy.
However, you can also gain direct admission after class 12th PCM to join as deck cadets. For direct entry as deck cadet, you must undergo a basic pre-sea training.
I hope it helps.

M.Sc or PG Diploma programs can be pursued by graduates to specialize in areas within the field of radiography.
Some well-known areas of specialization includes:
1. CT scan.
2. Fluoroscopy.
3. Angiography.
4. MRI.
5. Mammography.
6. Sonography.
7. Surgical radiography.

No, it's not necessary for you to opt for mathematics as an additional subject. As you opt for animation field, you will be taught pre-production. I would suggest you to take any of the fine arts subject instead as it will help you in future.

The eligibility criteria is different for each university and college. As per my knowledge, the minimum criteria is 50% in class 12th with PCB.

You can choose any field in which you have interest. You can go for engineering, B.Sc, biotech, hotel.management, fashion designing, CS, law etc. You can choose any course according to your interest area.
