CHM1321/1721 (Winter 2019)

CHM1321/1721 Midterm and Final Exam Tutoring Sessions.

Your instructor is a Ph.D. graduate from the University of Ottawa specializing in chemistry. With expert guidance you will be able to tackle your problem sets and be ready for your midterms or final exam. Complex mechanisms will be simplified. Difficult concepts will be understood. You will learn how to approach problems through the eyes of an expert and you will become an expert yourself!
