lol, dolls, don't be so damn stressed! bio is an easy course okay! just remember:
1. year 11 counts for nothing. you will use basically nothing you learn in yr 11 in yr 12 bio all right?
2. the bio course may look long i know, but you will find that you have plenty of time. if you don't like the way your teacher is handling the course, either borrow or buy a good textbook, manby go through the syllabus dot points individually which is all you need
3. i'm a bit hazy on this, might be wrong but, the Charles Stuart University websote had good notes for HSC bio, covered basically all units bar electives. i don't know whether they have prelim as well, but you could check it out and see.
4. Disregard this is you want but: the attitude you're displaying towards helping others is rather distressing. the purpose of this site is as a forum to ask for help and to help others. Think how you would feel if in every forum you went to everyone refused to help you until you'd shared knowledge with others? we all find bluders annoying, but many people juts need a little help with one or two areas and are willing to help you in return if they can - try to be one of those people
