Mathematics is high on the list of "you can't fall behind and cram". This is true not only within a single class but from class to class. Aren't fluent in manipulating equations? Calculus is going to be misery. Don't know calculus like the layout of your bedroom? Differential equations aren't going to happen. All the way back to `2+3 = 5` in first grade. If that doesn't go well, the rest will likely not, either.
