You won't succeed on any advanced test, with or without reference materials, if you haven't mastered the underlying basics. There would be too much to look up.

You won't succeed on any advanced test, with or without reference materials, if you haven't mastered the underlying basics. There would be too much to look up. You can't simplify fractions in a reasonable time if you need to look up everything in a multiplication table, for example, and it's true for everything that builds on that. It's the same for any topic: there comes a point where you can't succeed on Google alone.
