this time.
Step-by-step walkthroughs for Calc II, AP Stats, and everything in between — written the way a tutor explains, not a textbook.
Try this problem
Real problems. Real solutions.
Every session starts with the actual problem in front of you — not a generic explainer, but your specific confusion, untangled.

"I've read this page four times and I still don't get it."
Textbook explanations assume you already know the thing they're trying to teach. Integration by parts shows up in a single paragraph with no worked examples.
We walk through it like a tutor sitting beside you.
Student submitted the problem set at 2:17 AM. Got an 89.

"My exam came back with red marks I can't decipher."
A -12 in red ink tells you nothing. Students need to understand why the logic was wrong, not just that it was — especially before the next exam.
We rebuild the logic from the mistake outward.
Retake score: 76 → 91. Same student, two weeks later.

"My son's teacher explained it once and moved on."
Polynomial long division isn't intuitive. When a teacher moves at class pace, the students who need three more examples get zero. Parents end up searching YouTube at 10 PM.
As many examples as it takes. No moving on.
His next quiz: 100%. Mom emailed us just to say thank you.
Whatever's on the problem set, we've seen it.
From a single equation to a full proof-based assignment — every level, every subject.
Calculus
Limits, derivatives, integrals, series. From AP Calc AB to Calc III.
Algebra
Equations, factoring, systems, polynomials — the foundation everything else builds on.
Statistics
Probability, hypothesis testing, regression. AP Stats and beyond.
Linear Algebra
Matrices, eigenvalues, vector spaces, and abstract proofs — demystified.
Geometry
Proofs, theorems, coordinate geometry, and the logic behind shapes.
Discrete Math
Graph theory, combinatorics, logic, and proofs for computer science students.
The grade is the proof.
Before and after — real scores, real students, real subjects.
"I submitted my first problem at 11:45 PM and had a full walkthrough by 12:20. I actually understood it — not just copied it. That's new for me."

"My daughter was in tears over AP Statistics. After two sessions with Proof, she was the one explaining confidence intervals to me. I was stunned."

"Three weeks before finals I had a C in Linear Algebra. The eigenvalue explanations here are better than anything in my lecture notes. Ended with a B+."
Your first problem, solved free.

Everyone Makes"
A 14-page PDF written by our tutors covering the most common errors we see — chain rule slip-ups, sign errors, u-substitution traps — with correct worked examples for each.
