One subject, taken properly,
from the beginning to the end of it.
The Explorations go wide: many kinds of problem, one at a time. The Deep Dives go deep: one subject, taken all the way.
Each is a complete programme in a single subject — thirty sessions, forty for Economics — built from first principles rather than from formulas. Nothing is issued. Every rule is derived, in the room, with the students doing the deriving. A conversational programme textbook is written for each one, and every session comes with a problem set and full written solutions.
They assume light prior knowledge and nothing more. Calculus opens with what a function is. Organic chemistry opens with why carbon and not silicon. If a student has met the subject before and it did not land, these are built for them just as much as for someone starting cold.
These do not run in sequence and none is a prerequisite for another — with one exception: Physics Two assumes the mechanics of Physics One, or equivalent grounding. Otherwise, take whichever subject is yours.
From “what is a function?” to differential equations. Nothing assumed.
MathematicsFrom describing data to inference — and knowing what a p-value does not mean.
PhysicsMechanics through thermodynamics — the physics of things you can see.
PhysicsElectricity, magnetism, waves, optics — and where Newton stops working.
ChemistryNot a list of reactions. Shape, electrons, and consequences.
EconomicsMicro, macro and international — human behaviour, described mathematically.
| Programme | Subject | Sessions | Hours | Per student |

| Statistics | Mathematics | 30 | 45 | $1,000 |
| Physics One | Physics | 30 | 45 | $1,000 |
| Physics Two | Physics | 30 | 45 | $1,000 |
| Organic Chemistry | Chemistry | 30 | 45 | $1,000 |
| Economics | Economics | 40 | 60 | $1,250 |
One payment per programme. Early cohorts keep the price they joined at, permanently.
No. Each programme is built to be entered cold — light prior knowledge, not concept-zero. Calculus begins with what a function is. A student arriving from Explorations has an advantage in confidence rather than in content.
Because these are the only courses here that promise mastery of a whole subject, and that cannot honestly be done in twelve weeks. The shorter courses elsewhere on this site are shorter because they are answering smaller questions.
Not by design, though Physics One and Physics Two together cover essentially all of pre-university physics, and Economics covers micro, macro and international in full. Students preparing for examinations do well from these — but the programme is built around understanding the subject, not around one board's paper.
Honestly: because they are not built yet. Organic is the one with the worst reputation and the greatest need, so it came first. If there is enough demand for them, they will follow.
Yes, and several are designed with that in mind. Calculus and Statistics in particular are frequently the right thing for someone rebuilding a subject years later.
Tell us the subject and roughly where the student is now. We will tell you honestly whether to start here or somewhere earlier — and if the answer is somewhere earlier, we will say so.
