For students
How to use these notes.
These are companions to lectures — not replacements. Use them in the order below and you'll get more out of the time we spend in class.
1 · Read before class
Skim the unit before the lecture. You'll absorb three times more in class.
2 · Code along
Don't just read code — type it out. Run it. Break it. That's where understanding sits.
3 · Do the review questions
Every unit ends with review questions. Treat them as a self-test, not optional homework.
4 · Ask in class
If something in the note is unclear, that's exactly what office hours and class time are for.
"Read slowly. Code daily. Ask questions without fear."
