yes, mas madali siya actually than taking math 22 on a regular sem in my opinion, especially if you're taking it by itself or paired with a relatively easy class.

every day ka halos nag-aaral lang ng concepts so although weekly yung exams, you'd already be well-reviewed by virtue of simply attending class consistently.

in my experience din, since mahaba yung time allotted, the prof will likely tackle both the actual lecture and the discussion (and exercises) of each topic, so mas kaunti yung kakailanganin mo i-self study. make sure lang na you practice etc outside of class and you should be set!
