For students aiming for 800 — and the parents supporting them.
Hand-picked from the problems that separate a 700 from an 800. No easy filler — only the questions that decide top scores.
Not an answer key. Each problem is solved step by step — the reasoning, the traps to avoid, and the fastest path to the answer.
Written for students and parents serious about top-tier admissions who want the last, hardest points on the math section.
In this walkthrough Will takes one of the 100 questions and shows the full thought process: what the question is really testing, the trap most students fall for, and the cleanest route to the answer.
Will has tutored the SAT full-time since 2013, coaching students into Harvard, MIT, Oxford and beyond. The 100 questions in this guide are the exact problems he pulls out when a student is stuck between a strong score and a perfect one.
Not a random pile of problems — a deliberate spread across the topics that actually cost top scorers points.
These students started at different scores, worked on different problems and needed different amounts of time. The numbers show the result. Their own words explain the rest.
100 questions, a full worked solution for each. One download, yours for good.
One hour with a high-end private SAT tutor typically runs $180–$400. This is the whole method, once, for less than a single session.
Everything students and parents ask before buying
A PDF covering 100 SAT math question types, the ones that separate a 700 from an 800. Each one is worked step by step: what the question is testing, the trap most students fall for, and the cleanest way to the answer. Most question types also come with 2 to 5 variations, so you see the same idea show up in a different form and learn to recognize it, not just memorize one problem.
Students who are already scoring well and want the last 50 to 100 points. If you’re still missing questions in the 500 to 650 range, this guide will feel too advanced. It’s built for the gap between a 700 and an 800.
