The beat the song is built on is one bar, played through bars 10-16, 18-24 and 26-31, and 8 more places -- 40.9% of every bar the kit plays. Learn that one and most of the song is already under your hands.
It is played on hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 55 out of 100 -- a step up -- and the thing that decides that is the independence between the hands and the feet.
The whole song is 67 out of 100, so the beat is not the hard part: what costs you is everything around it, the joins and the fills.
A part this hard is not learned by playing it slowly and hoping. The room opens it on its simplest reduction -- the timekeeper alone, at 98 BPM -- and adds the notes back over 4 rungs, each with a tempo to reach and a gate to pass before the next.
Tempo goes 98, 115, 133 and 150 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.

Bars 10-16, 18-24, 26-31 and 42-44, and 7 more places. The time is kept on the kick and crashes to start with, and it changes 1 time over the song.
55 out of 100 on its own -- a step up. The song as a whole is 67 out of 100: demanding, mostly on the independence between the hands and the feet.
