Basic Math SelfAssessment
These math problems represent prerequisite skills that you'll need for statistics and other quantitative classes at UB. These skills will not be taught in class (except for those assessed in problems 1826 which are taught in DVMA 93). However, you can prepare before classes start by using the resources listed in the last column.
We encourage you not to use your calculator on this quiz except where indicated. Answers are listed below.
