A four-week TEAS plan built on a diagnostic
Start with a diagnostic, not with a book. Two findings from learning research shape this plan: testing yourself on material helps you remember it better than rereading it [1], and practice spread over days beats the same practice crammed together [2]. Both rank among the highest-value study methods in a large review [2].
Week 1: measure
Take the free diagnostic with your program minimum entered. Write down each section percent and the three weakest topics. Compare each section with your minimum: the sections furthest below it get the most time.
Week 2: close the biggest gap
Four short sessions (30 to 45 minutes) on the weakest topics, as timed sets of 10 questions. After each set, read why every miss was wrong, then redo the misses two days later.
Week 3: widen and time it
Add your second-weakest section. Do one full-length practice test under the real clocks (209 minutes with a break after math, as ATI describes) [3].
Week 4: confirm, then rest
Take a second full test early in the week. If every section is at or above your minimum, drill only misses. The day before the test, stop: sleep matters more than one more set.
