NTVY014 (Physical education I) [swimming] - we finally did proper backstroke, arms and legs and everything! and also breaststroke legs but on stomach, still no breaststroke arms though

NMAI057 (Linear algebra 1) [lecture] - attributes of inverse matrices, attributes of regular matrices, and matrix equations, after we started with groups and its axioms: association, neutral term and inverses.. also abelian groups

NMAI057 (Linear algebra 1) [tutorial] - quiz, i thought my solution was good but i must have made a small computational error because when plugging in my answer on the first row it was off by two and i didn't find the error, after the quiz we did proofs of matrix arithmetic statements, then matrix multiplication.. one is clearly easier, but either can appear on next week's quiz
