Field notes
The homepage lays out a progression from computational thinking, data structures, algorithms, and a visual-first math toolkit to language modeling, autograd, attention, and a Transformer. Learners who score 11 on the 12-question placement check are told they can skip Python foundations. The page also describes a tutor that uses the lesson and learner code to offer hints, not answers; these are presented as course features, not independently verified here.
