Best of luck to those applying this cycle!
If I could make a suggestion? I wouldn't necessarily aim to have it "done" in three weeks. The Bundle did magic on my LG game, but it took time. At first, I couldn't even get 10 right (let alone understand what the hell I was doing). Leading up to game day I was averaging -1 on fresh PTs, and on my actual exam (PT 73) I went -0.
I'd suggest working up and down all those LG sections and doing at least one full section per day--utilizing JY's explanations on the ball-busters. I think over time you'll be amazed at how easy they become.
(And FWIW, I never practiced my non-PT sections timed. I cared more about working through every set up/question till I did understand what the hell was going on. Speed came naturally.)
