Based on talking with the academic skills coordinator at my school, plus upperclassmen, I have Rx for a year, FA, Pathoma, and SketchyMed for a year (all 3 courses). I looked into Boards & Beyond but decided against it (resource overload). Will get UWorld for dedicated. Tried Firecracker and hated the format - Bros is the same but free.
If you email the B&B customer service and straight up ask, they'll give you a discount code (just mention which subscription you're looking into purchasing and say you'll pass it around to a few classmates).
