and hm.. Why do we always have to buy the new edition books when there're not much new info in them? it's like wasting our money to get some junk in the new books that we'll never use/need.. I'm not sure if it's the same for every book.. I'm just wondering if I should get the 7th edition of mat 307 book or the 8th edition.. *sigh*
btw.. there's no textbook needed for cse 142???
