Just got the game. After doing the Intermediate tutorial and messing around in Practice mode with every character, I thought I'd try the Challenge mode. I picked Noel and got as far as Challenge 03 when her first proper combo shows up. In case you can't remember, it's A, A, 6A, C, SJC, B, C, B, air jump and then another normal hit or two follow by an air special. I've been trying for at least half an hour now and I can't even connect the first B after the super jump cancel. Most of the time I screw up the SJC, sometimes I don't even get the 6A to come out, sometimes I fudge all the controls and end up doing her midrange gunshot attack on the guy as he flies away from me (looks kind of cool, but still...). I've got to the point where I'm SJC'ing after him about 50% of the time but the B has yet to connect. So basically, what the hell? Do I suck enormously at this game or is there some trick to it... Or is it just hours more practice on one part of one challenge for one character? I am absolutely dreading the later combo challenges.

Thanks for the explanation. It's these kinds of crucial basics that tend to hold me back in fighting games; I tend to just kind of run off instinct without really having a reason for doing what I'm doing. Since I'm learning BB from scratch when it comes out here on December 3rd, I'll be able to build up my learning nicely rather than inheriting loads of bad habits like I do whenever I play a new Street Fighter, Tekken or Soul Calibur.
