How can I find grammar mistakes in my own writing?
Check one layer at a time: subject–verb agreement, time and tense, noun countability, verb patterns, then sentence boundaries. Reading only for meaning makes it easy to miss a small grammatical mismatch.
What should I do after correcting a sentence?
Explain the reason, then write a new sentence with the same pattern. If you fixed “an advice”, try “some advice” and “two pieces of advice.” A new example checks whether you learned the pattern rather than remembered one answer.
