Join MAAC -maya academy for animation and cinematics
if you can, then join frameboxx, it has some very good specialisation programmes. MAAC is decent but courses at frameboxx are more industry oriented. MAAC is well known only because it is old. Frameboxx opened only at the begining of this year but its courses are better. And the fact is frameboxx is opened by senior technical staff from MAAC.many old & experienced faculty members are its founder. Believe me it will guide you well. But the most important thing you should do is go to the institutes & talk to students & not the management staff.if you can, check out student works of the institutes.
If you've completed your b.com, i advise you to join a shorter 6months-1yr course that has 1 or 2 softwares.theres no use learning all the softwares that these institutes teach because in the end you'll have to specialise in one single department and prepare a portfolio/showreel that showcases your best work in that particular department.during interview,the animation studios will ask you questions from your field & wont even ask you how many softwares you know.try to choose a course that has- basic sketching/drawing, photoshop, maya(it is preferred over max in studios) & any one compositing/editing software like after effects.the combination of these softwares will effectively guide you through the world of animation/visual effects & will be enough for you to prepare your showreel.
But remember to talk to students.you can also visit tasi.com for more info.
