I wouldn't worry about it, sounds to me like you are already well more qualified than 1/2 the class will be. If you can hit the target well at 15, 25, & 50ft (1 and 2 handed) then the rest is easy. The firings are timed but not critically (like in a league) and in my area they really don't focus on clearing malfunctions, they just discus them. Classes in my area give you 2 attempts too. Those who fail in the morning can get some 1 on 1 after the classroom work and then they have a 2nd chance to shoot at the end. Not sure if it's that way everywhere though. Bring a decent gun and you'll do fine. Those who struggle usually have a problematic gun (borrowed from a friend half the time) or are using a pocket pistol. I carry a Cougar but I always bring the 92FS to qualify ... the 92 makes it easy.
