School is a shortcut, if you get in one you'll learn faster.
Try the entrance exam if you can, maybe it will give you an idea of your current level.
If it's only been six months since you started animated/drawing it will be extremly difficult to achieve the same kind of work you do in school all on your own. There are some course online ( schoolism and stuff like that) but they are mostly master classes, not dedicated to beginners.
I really don't think online classes can replace direct criticism from someone of experience.
Anyway you'll need to work a lot.
Good luck
