I suppose cartoon and manga style drawing.
What's your current skill level?
What's your motive for learning to draw? Are you going to be making comics, games, animation, hobby etc.?
Whatever the case, you'll need to learn the fundamentals. Majority of the great masters of cartoon, manga, and fine arts -- no matter how simple their style is -- have built pillars on academic concepts: colour theory, anatomy, perspective, conceptualization, execution and so on. Watterson and Schulz, Tezuka and Oda, Picasso and Klee all have strong academic works under their belt before they've come to be known for their fame.
That said, I don't think you need to invest too much on the fundamentals, learn what you need, assess and critique your work and practice the right parts to help supplement your art. The resources are everywhere on the web so you really don't need to pay for education anymore (unless you use it for networking and hanging out with peers).
