I think the reason people are going off on this guy is that he's touting something that's essentially impossible and doesn't set a good example. It's anxiety inducing for M1s and laughable for M2s. The fact is, everyone plans to do 100 things and ends up doing 50. That's standard. Pretty much everyone plans to do UFAP at least 2x and a ton of people don't even manage to get through it once. The people who do really well plan for 200 and end up hitting around there. He's planning to do 1000.
From someone who is in the thick of it right now, trust me the plan is impossible, poorly thought out, and a recipe for burnout, exhaustion, and a very bland resume (and life, but that's not for me to judge). I could go into the specifics of why the plan isn't even good for USMLE, but it boils down to reviewing before any real learning has been done. He's going to ignore his classes and end up with a very surface level understanding of everything. He'll be trying to do so much in terms of quantity that he won't give himself the time to slow down and think about the things he makes mistakes on. Meanwhile, he'll be completely ignoring M1 material, which, even if it's not step 1 relevant, forms the basis of your knowledge for understanding path/pathophys/pharm.
I went down this same road, trying to do sketchy, UWorld, RX, Kaplan, Goljan, B&B, Zanki, and Robbins Review for every block. Tons of resources, and still not half of what he's proposing. I was beating my head against a wall. I would come across something I didn't understand, but I'd have to brush over it because time didn't permit me to just calm down and think through the concept. I kept telling myself it would all sink in later. I'd have time over break. That time never came. There was too much material to cover all the time, and I was only trying to keep up with this stuff alongside classes, nevermind trying to finish preclinicals in a single year. I've since slowed down. I do UWorld blocks timed and random for all the things I've covered so far + the stuff I'm currently covering. Despite not having even covered all the topics I'm getting questions on, I'm sitting at 82% with 20% of it done. It's because I'm taking the time to understand the underlying concepts, which you simply don't have time for while "covering" tons and tons of review resources.
That plan is a recipe for waking up in March, 3 months out, and realizing that despite giving up your life and sanity thinking you were miles ahead of your classmates and competition, you never really learned any of it. Despite being able to rattle off high-yield step 1 facts after M1 summer, your classmates eventually caught up, and they actually understood the underlying concepts because they didn't just watch pathoma, do some flashcards, and call it a day for each section. The most successful people I know learned things right the first time around. He'll be spinning his wheels with this plan. Trust me.
