While math is not tested directly on the MCAT, you WILL be faced with a number of science questions where scientific notation calculations are required. **Without a Calculator!**

Scientific notation on the MCAT is a common source of panic, because unlike simple long multiplication and division, it’s hard to fall back on pen-and-paper method.

This MCAT Math Without A Calculator tutorial video will show you how to tackle scientific notation if it shows up in the form of addition, subtraction, multiplication and division.
