High order homotopy is frigging scary. Homology is much nicer as an extension of the basic material, but I never got into the subject.
They don't let undergrads take prelim exams at many universities so you can't "test out of" alg top. But most math departments don't enforce prereqs so you could just take advanced alg. top or 3-manifold theory or whatever.

You are as bad as a nazi and should be shot.
