Day 30 · Strategy Guide

Exam Day Preparation

You have done the work for 30 days. The last 24 hours are not for learning — they are for arriving sharp, calm, and ready to show what you already know.

The night before

Taper, do not cram. New material this late tends to shake your confidence in what you already have solid. Every prep source says the same thing: light review, then stop.

Read the Day 29 cheat sheet once, slowly, start to finish. Do a few practice problems you have already gotten right — the goal is the feeling of fluency, not new difficulty.
Skim your error log. For each repeated mistake, say out loud the one sentence that fixes it.
Pack your bag now: admission ticket, photo ID, several sharpened pencils, a good eraser, and your calculator — the exact model you have been practicing with, not a newer or borrowed one. Bring a backup calculator and spare batteries if you can.
Rest your writing hand. Section II is a lot of writing under time pressure; do not spend the evening on a long problem set.
No caffeine after about 2 p.m., so it does not cost you sleep.
Sleep a full, normal night. Two nights before matters even more than the night before, so do not save catching up for the last minute.

Do not take a full timed exam the night before

A rough score the night before rattles you for no upside. Save full practice papers for earlier in the week.

Do this

Do something normal and low-stress in the evening — a shower, a walk, an episode of something. Trust that the preparation is already in you.

Exam morning

Eat a normal breakfast with some protein — moderate, not huge, and nothing you have not eaten before. Bring water and a small snack for the break.
Wear comfortable, loose layers and shoes you can sit still in for three hours. Rooms run hot or cold and you cannot control which.
Arrive early. College Board's own data shows students who were on time with all their materials scored about 20 points better on average than those who were late or forgot supplies.
In the last 10 minutes before it starts, do nothing hard. Breathe. Let the material sit where it is.

How the exam is built

Section I — Multiple choice: 45 questions, 1 hour 45 minutes, worth 50% of the score. Part A is 30 questions with no calculator (60 min); Part B is 15 questions with a graphing calculator (45 min).
Section II — Free response: 6 questions, 1 hour 30 minutes, worth 50%. Part A is 2 questions with a calculator (30 min); Part B is 4 questions with no calculator (60 min). Each free-response question is worth 9 points across its parts.

Roughly 2 minutes per multiple-choice question, 15 minutes per free-response question. Flag anything slower and come back.
Multiple choice: answer every question — there is no penalty for guessing.

Note

The 30-minute Part A of the free-response section ends before Part B begins, and you may not go back to it with a calculator afterward — but you can keep working Part A questions by hand during Part B.

Free-response habits that earn points

Write the setup before the number. The integral, the derivative expression, or the equation you are solving each earn points on their own — even when a calculator does the arithmetic.
Show the calculator setup in real notation: $\int_0^6 v(t)\,dt$ , $f'(3)$ — never "fnInt(...)" or "nDeriv(...)".
Read the task verb. "Approximate" wants an estimate with the method shown; "justify" wants a sign fact or a named theorem with its conditions verified; "interpret" wants a sentence in context with units.
Justify with the derivative or a theorem: "because $f'$ changes from $+$ to $-$ ", "by the IVT since $f$ is continuous". Never "because the graph turns".
Carry units through every rate, accumulation, and average-value answer. Keep at least 3 decimals in intermediate steps; round only at the end.
Do not simplify. An unsimplified but correct answer earns full credit — do not risk an arithmetic slip cleaning it up.
If a later part needs an earlier answer you are unsure of, use your answer anyway and keep going. Cross out neat, do not erase.

Time budget

About 2 minutes per multiple-choice question and 15 minutes per free-response question. If a question is eating your time, write your best partial work and move on — a blank earns nothing, a setup earns something.

If your mind goes blank

Put the pencil down. Slow breath in for 4, out for 6, three times. The panic passes faster than it feels like it will.
Go to a question you know you can do. One solved problem resets your confidence for the rest.
For a stuck free-response part, write what you do know: the relevant formula, a labeled diagram, the integral you would set up. Partial credit is real.

One last thing

Thirty days ago some of this was unfamiliar. You have worked through limits, the whole machinery of the derivative, the Fundamental Theorem, and the applications that tie it all together. That progress is real and it does not disappear under pressure.

You are not trying to be perfect. A 5 does not require every point — solid work across the paper gets there.
Trust the preparation. Read carefully, show your setup, keep moving, and let the work you have already done carry you.
Walk in knowing you earned the right to be calm. Then go get your 5.

After the exam

However it felt, it is done — students routinely feel worst about sections they scored well on. Close the book and go do something you enjoy.
