Chemistry 30 - On-Demand

As a newcomer to Canada, I found it difficult to catch up with certain lessons and topics, especially with courses such as Chemistry. But, The On-Demand Review Package that RTD has was more than enough to serve as a review to me, with not just my diplomas, but also the exams and quizzes throughout the semester. The video recordings explained everything perfectly, and the questions had varieties which introduced me to several questions in the exams I took.
