Cambridge maths notes
Some years ago1 I read the Mathematical Tripos. Because my handwriting was even then famously awful, I took some time to transcribe lectures into LaTeX, and even released them on the then-new “WWW”. Over the years they’ve shifted around, and are now on github.
The Tripos has of course changed since those days2, but oddly-enough maths hasn’t and the notes are still found useful. You may of course note that Parts IIA and IIB no longer exist. After much debate by the faculty they were removed and replaced by Parts IIC and IID. Go figure.
