Choose a course.
Start learning.
Programming, mathematics, chip design, and English. Every complete course opens directly.
Programming
Start with Foundations, or open the course you need.
Mathematics
Stage means prerequisite depth, not difficulty. Chapter counts show course size. Open any course directly.
Undergraduate foundations
Number, algebra, geometry, calculus, linear algebra, probability, statistics, and discrete foundations.
Undergraduate major core
Proof-based analysis, algebra, differential equations, topology, optimization, and mathematical structure.
Master’s and graduate core
Advanced undergraduate transition and first-graduate work across analysis, geometry, algebra, topology, and probability.
Doctoral specializations
Bounded specialization cores with theorem control, counterexamples, literature orientation, and independent reconstruction.
Chip design
From digital logic to independently reproducible production evidence for one bounded digital ASIC.
English
A K–12-inspired path through college, work, and research. English by default; native-language support is optional.
