Study only Math when English and Reading already sit at target on two timed cores. Keep one short English or Reading section a week so those scores do not slide.
A Math-heavy week
Four Math sessions, one maintenance section on English or Reading, one error-log night. Official Math: Math practice tests.
The bottom line
Math can own the calendar only after the other two cores are already at the number you need.
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.
