They collect more problems. They do not get faster.

F=ma and USAPhO are not “do 400 random Irodov problems” contests. They reward a small set of models you can deploy under time: Newton with constraints, energy + momentum as a pair, oscillations, gravitation, circuits as graphs.

A better week looks like this:

• 2 focused topics, not 10.

• 1 timed set (50 minutes, no notes).

• 1 rewrite of every miss — not a glance at the solution.

If you cannot explain why an answer is wrong in one sentence, you have not learned it yet.

That is the structure inside the Sprint Plan. One offer, $47, lifetime access. Built for students 14–18 who actually want a contest score, not a pile of PDFs.
