Great clinical cases to learn from

I am having a lot of fun with the clinical case studies. I thought it would be too complex but it’s actually quiet Applicable to my every day primary care. In the case studies, you are given a CC and you create differentials. You slowly proceed through the case with more HPI, FHx, SHx, PE, etc during which you can change your differentials. At the end, you are given the answer and some clinical pearls/explanations. It’s great review!

This is a great app. I really enjoy the variety of cases and the stepwise processing of narrowing down your differential. I also really appreciate the teaching points at the end of the cases!

I wish there was some sort of save feature where I could save these teaching points to review later, or save the cases that I struggled with.
