jetsam

last night i played the hard puzzles on websudoku.com and really solved one of them by myself, although i took 14:17. websudoku.com says 70% are faster. but this is the first time i completed it, and i must tell shanghui!

i did a lot of the maths revision worksheet; finished summation and mathematical induction, vectors, complex numbers, and permutations and combinations.

and i missed you, but it's been only two days. i love you too.
