putting aside probability, i have no tutorial to do now. finally can read a bit on the material engineering quiz... only started off with the first 60 pages... got 600 more to read... think john ng would kill me if he knows this.

haiz, and s-papers.... physics is more exciting than expected, esp. some of the contents today can be related to matrix and basis... of course only f. math people can see it... haha, fun, esp when there's no right or wrong answer for some of the questions.
