Guys/gals. Chill. Some of the respondents on this thread are yet to even start medical school and they are already the most popular commentators on the 2018 Step 1 thread which is quite shocking to say the least.
Many of the study plans touted here are downright ridiculous.
For interested parties still working through the process of M1 and 2, focus on "super thoroughly" understanding and destroying your class exams (shoot for the 90s or as high as you can get). If you do this alone and are among the top 5-10% of your class, you will almost certainly crush your exam with a prudently spent 6-7 week dedicated period.
If you really want to do Step 1 related stuff while going through M1 and 2, again, focus on understanding using a tried and true resource (like Boards and Beyond) and slowly pound through a Qbank (does not matter which one UWorld, Kaplan, RX, pick one). THAT IS ALL (1 resource + 1 Qbank).
All these plans of using 10 resources will most certainly not be followed through so don't waste your time. The popular idea of abandoning coursework and focusing on Step 1 fully in most instances leads to ruin/the attainment of less than full potential. A solid foundation is never built without the basics. Most of the resources that exist are for REVIEW, not for primary learning. I am still baffled by how people still neglect their M1/2 curricula and suddenly expect to have a solid foundation from "review resources". If you check the stories of the 270+ folks, a common thread is that they almost all killed M1/2. No matter how low yield your curriculum supposedly is, spend the time and learn the material well THE FIRST TIME. It is usually quite easy to spot anki faithful who can regurgitate details as quickly as their names but then for some reason get hammered on Qbank questions/NBMEs. Review resource foundations generally don't hold up when subjected to the winds of well thought out questions.
TL, DR; Focus on understanding material and crushing your M1/2 coursework as priority 1. If you have extra time, priority 2 = find a good understanding based resource (like BAB) and slowly go through 1 Qbank.
Source-did the following and crushed all Steps.
Peace.
