GMAT: Scores → 14-Day Plan

I missed this question on a GMAT Official Practice Exam. Teach me why, don't just tell me the answer.

Section: [Quant / Verbal / Data Insights]
The question, with all answer choices (and the passage or figure if there is one): [PASTE QUESTION]
My answer: [MY ANSWER]. Correct answer: [CORRECT ANSWER].
Why I picked mine: [ONE LINE]

Please:
1. Explain why the correct answer is right. For Quant and Data Insights, show the steps (for Data Sufficiency, test each statement alone, then together). For Verbal, identify the conclusion and the gap or the passage lines that decide the answer.
2. Pinpoint the mistake in my reasoning and label it: didn't know the content / wrong method / misread / careless / timing.
3. Give me a one-line rule to use next time.
4. Write 2 similar practice questions (not official) with answers and short explanations. Before you show them, silently solve each one again from scratch. If your two solutions disagree, or more than one choice could be right, rewrite or drop that question. Show only the final, clean questions, not your checking.

Trust the official answer key. If it looks wrong to you, say so, but assume I made a typo first and ask me to check.

Help me choose my GMAT Focus section order and split my study hours.

Give me:
1. A short plan for each of the 3 days: light review only (no new topics, no full practice test the day before), plus sleep and food.
2. A checklist of what to confirm and bring. Include acceptable ID, my appointment time and time zone, and for an online test, the room and computer requirements. Tell me to confirm every rule on the official website, because rules change.
3. A pacing plan for each section and what to do if I get stuck or panic.
Keep it short and calm.
