“The geometry was hiding in the equation the whole time.”
— Priya R., Calculus II
Priya Ramaswamy
Pre-med, University of Michigan · Calculus II → A
Modules Priya used:
Visual Limits
6hEpsilon-delta proofs through interactive geometry — see the squeeze before you write it.
Integration as Area
8hRiemann sums animated from first principles. The integral stops being a symbol.
Series & Convergence
5hTaylor series visualized as polynomial shadows of transcendental functions.

Marcus Thompson
Electrician → Data Analyst · Linear Algebra Track
Marcus’s track:
Vectors as Arrows
7hLinear transformations shown as geometric operations — matrices become intuitive.
Eigenvalues Visually
9hEigenvectors as the axes that don't rotate. Suddenly the characteristic polynomial has meaning.
Interview Prep
11hData science interview problems with step-by-step visual walkthroughs. 47 practice sets.
Concept mastery over 11 weeks
Free chapter — no credit card needed
Every course starts with a diagram, not a definition.
We build intuition first. Formalism follows. By the time you see the theorem, you already know it’s true.
Calculus I & II
Limits, derivatives, integrals — every concept shown geometrically before algebraically.
Linear Algebra
Vectors, matrices, and eigenvalues as spatial transformations you can see and rotate.
Statistics
Probability distributions, hypothesis testing, and Bayesian reasoning through simulation.
Differential Equations
ODEs and PDEs with phase portraits — see the flow field before you solve the equation.
