It is also useful to practice hitconfirming. e.g if your combo starts with cr.LK, cr.MK, cr.HP with Beowulf, you want to only press the cr.HP when you hit the opponent, otherwise you will be punishable or have to cancel into a special which has its own problems. To practice this, set the dummy to block random first hit and then practice doing cr.LK, cr.MK and confirm into cr.HP if you hit and if not then stop.
