“I just wanted to let you know that I got into Cornell ED a couple of months back, and I just remembered how I should have told you. After all, you helped me for months on end with SAT work and made such a painful exam so much more pleasurable.”

“Every student I taught had the same problem in a slightly different shape. They didn't need to drill more questions. They needed someone watching which questions they got wrong, and why. The 1600 Game lets me sit across the table from a student, at scale.”
On the hardest subject-verb questions, the right answer is the outlier. Three plural and one singular, or the reverse. A twenty-year pattern, in a ten-second game.
The senator's repeated insistence on her independence from the party establishment was, the columnist noted, hardly _____ given her decade of votes aligning with leadership.
You're right — they're cousins. Both are about whether the claim holds up. But one is about the claim itself, and the other is about how the claim lands on a listener. Which is which?
Exactly. Now go back to the second half of the sentence — “a decade of votes aligning with leadership.” Are we assessing the claim, or the listener?
Don't know an answer? Stuck between two choices? Confused after getting it wrong? Open a chat right there on the question. A Socratic tutor walks you to the answer, without giving it away, and teaches the move that got you there, so it transfers to the next question.
Socratic, never spoiler. Asks the next question instead of handing over the answer. The student learns the strategy, not the keystroke.
Mistake-to-mastery quests. Every wrong answer spawns a focused drill on the exact concept that broke, until it's no longer a weakness.
Strategy in context. Once the student gets it, the tutor names the move that worked, so the next question of the same type is faster.
Mastermind walks into every conversation already knowing your predicted score, your target, your test date, your weaknesses, and every score report you've ever uploaded. The strategist part of working with a great tutor: the part where they sit you down and say here's what we're going to do for the next six weeks, and here's why.
Reads your real score report. Upload a Bluebook PDF and it reads all 8 K&S domains correctly. Most readers misinterpret the bars.
Builds a real study plan. Priority subcategories, weekly session targets, dated milestones. Update it in conversation, the app reflects it instantly.
Prioritizes ruthlessly. Grammar and algebra before slow-moving reading domains. Where your prep time actually moves the score.
Two sessions on Quadratic Equations, one on Systems of Equations. Your last score report flagged both as priority — and your accuracy on Quadratics dropped from 72% to 58% over the last two weeks. That's where the score is leaking.
Reading is holding steady — let's not touch it this week. I added both to your plan.
And remember — great minds proceed by the smallest of stages. There are only a handful of question types in Quadratics, same with Systems. Learn the first moves and the hard ones become easy.
Every concept the College Board tests, taught by a tutor who has seen each one blow up.
Written and calibrated to mirror the real test's difficulty curves and the patterns the College Board favors.
And growing. Each one teaches a trap the test maker structurally cannot tell you about.
What students and parents have sent after test day.

We went out to dinner last night, and I told her I was glad she was getting some downtime from school. I caveated with “of course you're still doing work with Jeremy.” She immediately interrupted and said she absolutely loves working with you, and that “Jeremy work” is some of her favorite work. She said she loves how you move through things quickly and never repeat yourself. Just thought you would like to know.
