Solve It Again Cold

Three months ago you solved 60 problems. Interviews are in six weeks. You have four hours this weekend, and your goal is to retain what those 60 problems taught you.

Karpicke and Roediger had subjects learn word lists under different schedules of study trials (S) and test trials (T), then measured free recall one week later.

condition	one cycle, repeated 5 times	study trials	test trials	recall at 1 week
standard	study, test, study, test (`STST`)	10	10	68%
repeated test	study once, then test three times (`STTT`)	5	15	64%
repeated study	study three times, then test (`SSST`)	15	5	57%

Which use of the four hours does this support?

Skim all 60 statements and, for each, write one line naming the technique you used.

Pick 12 of the 60 and re-solve them from an empty file with nothing open, then diff against your old code.

Re-read your own accepted solutions to all 60, about four minutes each.

Re-read the editorials for the 15 you found hardest, since those hold the most information per minute.
