Huh? Why would you need to multiply vectors on the MCAT?

 

[UseUrHeadFred]

Uh, you should probably try a practice test. Vector multiplication shouldn't be found on the MCAT.

you do not need to do ANY vector multiplication on the MCAT

there are a couple of formulas (e.g. torque) that are based on dot or cross products, but all you have to do is just memorize the formula itself
