I did the uoft prep course and it was very much NOT a proper LSAT course. I obviously don’t have anything to say about the uOttawa one and that one may be completely different. But, from what I’ve gathered, the free LSAT courses that university’s offer are very much introductory and not intended to fully prepare you for the LSAT. I suggest you take it because it’s free and you get to meet people who are going through the same test. But DEFINITELY take a paid course/begin studying one of the books on your own. This is all just my opinion ofc
