I never learned much chemistry. My vague recollection is that it involved way too much memorization for me. For math and physics, you only have to memorize a few formulas and constants (maybe today's students are permitted to have them all programmed into their calculators for all I know).

The awful thing about physics and engineering, IMO, is that you have to carry over numbers and decimals and units for pages and pages, and at the end you've dropped some decimal place 30 lines ago, or have ended up with an area in cubic meters, and you have to go back and check every all over again.

Much easier to do math. It is usually clear when you have the answer. The theorem is proved, or it isn't.
