Drills
Practise one part of the solve at a time: the cross, F2L, the last pairs and your lookahead.
About this drill
The cross and two pairs are solved: finish the other two. Lots of F2L repetitions without redoing the start of the solve. For advanced solvers: during inspection, plan both last F2L pairs move by move, then close your eyes and solve them from memory. It trains seeing ahead.
Connect a smart cube: it sets each drill up with you move by move, starts on your first turn and stops by itself when the drill is done.
Preparing…
SPACE starts and stops; the next scramble follows.
Got a smart cube? It sets each drill up and times it.

Every drill isolates one part of the solve, so a minute of practice gives you far more useful repetitions than full solves do. Scrambles are random-state: the part you drill is solved, everything else is truly random. With a smart cube the drill judges itself and moves straight on to the next one.
