Study Timeline for someone taking STEP in M3 (after rotations)

[Hippocratesintheflesh]

Hi everyone, my program has me taking STEP following some clinical rotations (post-Christmas break M3 year)--As I haven't had a chance to talk to many of my peers who use 3rd party resources, I was wondering if any of you M2/M3/M4's who had a similar STEP schedule could give me some advice

I was thinking something alone these lines, roughly:
M1: B&B
M2: Start Zanki--in addition to B&B, Pathoma, Sketchy Micro
Summer before M3: USMLE Rx Practice Q (continue to review aforementioned resources)
M3: Do official USMLE materials/touch up via First Aid and other resources

Please let me know if you have any tips or suggestions--I'm particularly curious about how people manage to study for STEP while actively doing clinical rotations (because thats what I'm pretty much doing from the 2nd half of M2 until I get to dedicated)

Thanks in advance!
