 ## Questions
 
 ### How can I review the math prerequisites?
-Many OSSU students choose to review math topics that they have not studied recently.
-OSSU recommends students use Khan Academy for such a review.
-Below are links to topic assessments.
-After taking an assessment, you should have a clear idea what topics to study, and resources on Khan Academy to use.
