Choosing
Which should you use?
If budget is tight, Argonaut gives you a complete Step 1 and Step 2 CK bank for $48, with no clock running on your access.
If you want the largest bank and can afford it, UWorld is the bigger product. Many students add Argonaut as a second bank for fresh questions and ARGO's weak-spot sessions.
