Why it sticks
Don't stop at reading the correction.
Fix your own sentence, then rewrite it. That one loop carries into the next draft.
A textbook can't fix your sentence
Rules and model answers don't tell you what to change in your draft.
Correction on the English you wrote
See where to fix — and why — based on your answer.
Reading a model rewrite isn't enough
If you only look at the right version, the same spot trips you next time.
Choose points to practice
Pick which of several corrections to practice in this draft.
Mistakes return if you leave them
Understanding once fades if you don't use it again.
Rewrite the points you chose
Don't stop at reading the fix — rewrite the points yourself, then Review and Test confirm they stick.
