Using proportional reasoning lets us find quantitative and qualitative answers to Physics and Math problems in a fast and easy way. This 4 page tutorial explains a three step process for approaching these problems, and also has 6 completely worked examples to help the student become a master at solving proportional reasoning problems. Great prep for the AP Physics and other standardized Physics exams.

This is a quick 1 page reference sheet that contains 20 SI prefixes, the 7 root SI units, and an explanation of how prefixes and units combine to give re-sized units. Also defines Liters and millilters in terms of SI units. A very handy reference sheet.
