i've got the excel sdd book. in conjuction with my teacher's notes it was pretty fab. however it can't teach you to not miss a page in the hsc paper. *anger at my stupid self*
regardless, it's up for salee ! i took out the study cards at the back which are srsly amazing. but i still have them intact etc. so yeah. rrp is $31.95. you can get it off me for.. 20 bucks ? i only used it the day before the hsc so new as.
