When five minutes remain, stop starting new hard items. Finish a nearly done one, then fill every blank. Nothing left empty is in the no-blank rule.
Close, then guess
A letter of the day fills the rest, in letter of the day. Reading in that last window is in five minutes left in Reading. Science is in five minutes left in Science.
The bottom line
Five minutes: no new walls. Fill every remaining bubble.
Start practicing
Start with a free diagnostic, then drill your weak spots with 15-question quizzes and track how you're doing across Reading, English, and Math. Compare plans whenever you're ready to go further.
