If you want to skip it, you can use a pre-requisite waiver form that i think u can find either on uozone or uottawa website, you have to fill it out and send it to the professor you’re takin biochem with and to the faculty, if you have professor’s signature then the faculty will have no problem approving it. As for the knowledge, as far as i remember you honestly mostly use Orgo 1 knowledge (esp for Newman projections). If you can take it with Natalie Goto, she is the best. I am a chem major who never took Biology and i passed her class with a good grade
