SDN Members don't see this ad. (About Ads) Has anyone ever prepared for the pcats through youtube tutorial videos? Besides the verbal section...for the visual learners, I feel that the youtube tutorial videos on chemistry and biology is extremely helpful. All the sections that I forgot since college, I've looked it up on youtube and there seemed to be a lot of videos to help you out. I was wondering if anyone else has tried this method. btw I'm not saying that you only have to use youtube to prepare but I feel that it is a great supplement to the overall preparation.
