Databases
Build the universal mental model that every database is implemented against — the relational model, schemas and keys, indexes, transactions, concurrency, PostgreSQL architecture, production operations, modeling patterns, and the modern data ecosystem (NoSQL, distributed SQL, warehouses, vectors, streaming).

Mathematics
A comprehensive, 5-pillar curriculum that builds a complete mathematical education from foundational reasoning through advanced applications. Covers proof writing, algebra, trigonometry, the full calculus sequence, linear algebra, abstract algebra, discrete mathematics, probability, statistics, optimization, game theory, and mathematical modeling. Designed for polymaths who want deep mathematical fluency and strongest when paired with career tracks in data science, software engineering, or quantitative fields. The specific applications evolve but the mathematical structures — groups, spaces, measures, graphs — are eternal.
~1075h
Law
Legal literacy — how law actually works. The trunk gives you the operating system: where law comes from, how courts and precedent work, contracts, torts, property, criminal vs civil, and constitutional structure. Clusters dive into reading cases, contract mechanics, IP, your rights with police, and the startup legal toolkit.
Environmental Science
A rigorous curriculum on the Earth as a coupled system — its biogeochemical cycles, ecosystems, climate, pollution pathways, and the sustainability and policy frontier. Built for working professionals who already had a weak intro environmental class and want a complete, mechanistic mental model: how the carbon cycle actually works, why climate models project what they do, where pollutants travel, and which interventions move planetary boundaries. Every course pairs scientific mechanism with a real-world implication so the learner can reason about environmental decisions, not just recite definitions.
~320h
Sales
A working understanding of the craft of selling — buyer psychology, discovery, qualification, objection handling, negotiation, and pipeline math. The trunk walks one complete deal motion from prospect to close to expansion; clusters dive into outbound mechanics, discovery frameworks, objection playbooks, negotiation, founder-led sales, and enterprise deals.
Psychology
A working understanding of psychology — what the science actually claims about how minds, brains, and behavior fit together. The trunk gives you the orientation a literate professional needs (how psychology knows what it knows, the brain behind behavior, learning, memory, decision-making, emotion, personality, social influence, development, pathology, and what therapy does); clusters dive into research methods, perception, cognition mechanics, social influence tactics, the field guide of disorders, applied behavioral science, and the psychology of everyday life.
Algebra & Precalculus
The foundation curriculum that prepares you for any university-level math course — calculus, linear algebra, discrete math, statistics. Builds symbolic fluency from variables and equations through functions, polynomials, exponentials, trigonometry, and the proof and set-theory groundwork that modern mathematics rests on.
Frequently asked questions
What does the Databases roadmap cover?
1 courses broken into 12 bite-size concepts, each taught as an interactive lesson with quizzes and spaced review.
Do I need prior experience to start?
No. The roadmap starts from fundamentals and builds in prerequisite order — each concept unlocks the next, so you're never thrown into material you haven't been prepared for. If you already know the basics, a placement check skips you ahead.
