If two choices are both grammatical, the shorter one is almost always right. Extra words that repeat an idea are wrong. Annual already means every year. Past history, end result, and completely finish are the same mistake. Redundancy as a topic is in redundancy and wordiness.
Grammar first
Shortest is not a free pass. A three-word fragment still loses to a longer complete sentence. Check STOP versus GO, then pick the shortest legal option. Punctuation that decides legality is in STOP versus GO punctuation.
NO CHANGE can be the short, legal choice. Do not reject it because it feels too easy. That option is in NO CHANGE answers. Formality, when the issue is tone rather than extra words, is in formality.
The bottom line
Cut anything that repeats. Keep the shortest version that is still a legal sentence.
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.
