Animation

B.Sc animation and VFX are 3 years' duration courses.
Bachelor of Design (B.Des) course in animation is a 4-year course. The four years course includes 2D, 3D, VFX, etc. The difference between the two degrees is that the B.Des course is not only 1 year more but offers usually an international syllabus, which is completely focused on Animation only. Few of the top colleges are Artemisia College of Art & Design, MIT, Pune, NID, Ahmedabad (the top in the country), etc.
While selecting college, consider factors such as the fee, whether the faculty has animation industry experience or not, whether the college has facilities such as its own animation production studio, whether the college teaches classical animation (base of all kind of animation) or not, etc. availability of equipment such as Light boxes, etc. should be there.

It depends on the institution mostly. Though animation is such a field where you can learn as many softwares as you feel like depending upon your free will to get your desired output. Normally, you'll be taught Autodesk Maya, Autodesk Match Mover, Adobe Illustrator, Adobe Photoshop, Adobe AfterEffects Monkey Jam, Blender 3D, and maybe a few more. This is a basic set of softwares which are mostly used for teaching students in institutions because they either carry free or institutional licenses. This means that these softwares allow a free access to students and teachers for learning purposes only and not for any commercial purpose. Other softwares like Nuke, Marmoset, etc. do not provide institutional or free licenses. So you can't expect your institution to teach those to you unless they've paid for it. In case you want to explore other softwares. You'll have to buy their license to use them. My advice: First learn the basics and once you become professional, buy professional software suites.
