Just how effective is challenge mode for a beginner to practice?

I know that for me personally, I was attempting to main Jin. The earlier challenges helped me see where I need to go with him as far as combos and such go. But like everyone else said, I think looking through the forums would do you more good in the long run. Also, there is one thing that bothers me about Challenge mode and it's that they put multiple combos in one challenge. Why not just have them be like chapters in one particular challenge? Eh, well that's enough of my rant.

They listened to you for CSX at least, 15 challenges for each character, one combo in each (Bar the first two, which aren't really challenges).

Challenges are holding me back from a double platinum in the blazblue games.

Can get a good run for my mains, but characters like Rachel and carl are just a pain to go through, yikes.
