Dot Point is Very Good only if ur really serious about Biology, it goes into so much detail, the questions goes on forever answering every dotpoint. gets really boring, i only did arounnd 15question in the whole book of around 300questions lol...
Success One on the other hand, has all past papers, the answers are really detailed which is a good thing, its easyer too use and u wont get bored of doing the questions. it also has a focus area, but the questions in the focus area are pretty crap coz the questions are so repetitive and the answers are so short.
I did found a new biology book however, which is better than both of them, its called BIOLOGY PAST HSC PAPERS WITH WORKED ANSWERS by Catherine Odlum and printed by ODLUM GARNER i think its new, coz i couldn't find it anywhere besides DYMOCKS.... the answers they good u is not long but consice, they also have notes at the bottom of there answers telling u some interesting information about why this is the case, or other possible answers. and its also cheapers, much cheaper, dotpoint cost me $42.95, Successone is about $30 and this one is only $21.
