I've heard it's not good for Step 2 CK but that was from people who did it about two to three years. I'm wondering if anyone has done it more recently.
Not bad actually , they are good to do along with his notes and vids .. Some are pretty simple just to hit main point and some are Uworld style you can say . I'm doing OB now and so far he seems to hit the major points , i was clueless on OB before starting his Vids . My Ob rotation was over a year ago and pretty much spent it in OR, not much time on wards
I did DIT for Step 2 CK. Probably shouldn't have spent the money in hindsight. I did well on it so maybe it helped but I would say its not necessary. I learned about OnlineMedEd videos at the very end of my 3rd year. I really wish I had started them earlier. They are wonderful.
