NTVY014 (Physical education I) [swimming] - swimming with flippers! just backstroke though, it was a little fun although the top of my left foot hurt a bit after

NMAI057 (Linear algebra 1) [lecture] - finished skew fields with fields based on modular arithmetic and started vector spaces, including funky things like a vector space of systems of sets with the function of symmetrical difference

NMAI057 (Linear algebra 1) [tutorial] - continued on with permutations, one person decided to go do a problem on the board in front of the class and he was so bad at it it made the teacher rather mad.. it made me feel really bad but on the good side i comprehended all of what we went over!
