It's much tougher considering people in Erie's LDP pathway who attended post bac often had the same lecture slides and professors so in a way they "know" what the test and testing style is going to be like. For the first year at least.
Don't get me wrong, post bac gave me a bunch of medical knowledge, but I wasn't used to reading from textbooks for all my information. I realized last year I was oftentimes simply skimming trying to find the "bulletpoints" I needed to know kind of like a powerpoint would have. When I really focused and read the text book slowly and like a novel, I learned a lot more and my grades got a lot better.
That being said, I would stil highly recommend PBL simply because it makes you think and you learn how to "learn". When you are on rotations and the preceptor asks you to find out the pathophysiology of something, PBL people automatically know where to go and how to look things up. PBL also gives you early exposure to a lot of the tests real clinicians use to narrow a differential.
There is also the difference in lifestyle, LDP people have an exam pretty much every week so they are stressed all the time. You can usually tell who is LDP at the main campus because they are the ones that look like zombies haha. PBL gives you flexibility in when you want to learn so if you really want to just take a day off, you can and work hard the following day without stressing over next weeks test. Of course there are pros and cons, for example, most PBL tests have about 30-40 TEXTBOOK chapters. It's kind of ridiculous and downright scary at first, but you get used to and and will be surprised how much you can learn for one test. Also there are usually only 3 PBL tests a semester so if you fail one, it could be a very steep uphill climb to redeem yourself.
