Going to assume this is for step 1 based off all your other posts. You seem to be starting way too early if your only M2 out of a 5 year program and definitely risking burn out. If anything just do B&B and pathoma now as they'll be far more beneficial to your course rather than the specific minutiae in zanki. The majority of us (UK'ers) start taking step 1 seriously about a year out and so far the trend has been very positive with quite a few people scoring 230+. We've had people pass step 1 but fail the YSKT so be careful.
If this isn't related to step 1 then ignore it.
