Except that being good at math or being good at designing a web page have nothing to do with memorising formulas or coding. It's about being able to break down the problems into manageable pieces and applying your knowledge to bring structure to them. Which isn't something you can replicate with a tool, if you don't know how it's done in the first place.
If you know nothing about the general principles of math, you won't be able to solve problems even with tools, because you won't know which tools to use and how.
Isn't the point of being at a college... to learn stuff?
