All I would have done is the bootleg qbank stuff from first year. All of this can be done in like 2-3 days. I see these questions as wastable. From your list, that seems like too much studying. Ill just say this, I didnt study over the summer and Im so exhausted now that I honestly dont even care about my USMLE score (I do but I just kinda wanna get it over with) the way I did when i started second year. Rest in the summer is important so make sure u dont study too much. You gotta pace yourself, too much too early is disastrous if u cant get it together in the end (which can happen to me, if I dont get a kick in the ass soon). Look at the detroit pistons, they sucked all year and now they are playing like they can win it all. On teh flip side, cleveland cavaliers were in the playoffs, but couldnt do it at the end, and now lebron is talking about goign to the Knicks and Paxon the GM just got fired. This analogy should give u the message.
Anatomy - do old qbank/qbook
Phys -the same
Path - Do the chapters in Robbins Review, Webpath of the stuff u have learned
Embryo- First Aid if anything
Histo - look at the pictures in your atlas really quick
Micro - old qbank/ qbook or pretest (i havent used it but i heard its good)
This sounds pretty doable and pretty easy. Should give u give u plenty of time to chill and do research or whatever, and at the same time, doing this will give u enough confidence of your first year stuff that u wont have to worry about it when USMLE comes around.
again, i havent take the Step, im just telling u waht i would have done, and who knows how much it will help. so better advice can be given by the peeople who destroyed Step 1 here.
