Turn the exercises into a repeatable week
This is one possible arrangement. Shorten it, split it up or spend more time on the skill your errors reveal; it is not an evidence-based minimum dose.
First session: retrieve and listen
Recall a small set of words and one verb pattern. Work through a short audio/transcript pair and retain two errors to revisit.
Second session: read and write
Retest those errors. Read a short passage, justify your answers from the text, then write a short response and correct it.
Third session: speak and adapt
Practise a difficult sound with audio, read aloud and answer fresh questions without your script. Record one answer for feedback.
Next cycle: test the correction
Return to the mistakes without notes. Use a different sentence or task to see whether the correction transfers. Add occasional current-board exam practice alongside these small drills.
