For sale/trade: Chemistry & Biology textbooks

[genki]

now that im done with studying (for the moment) i have a couple of text books lying around that i thought someone here might be interested in. on offer is one copy of a year 11 and year 12 text for both chemistry and biology. these are the books i have:

Year 11 Chemistry Dimensions

Year 12 Heinemann Chemistry

Year 11 Heinemann Biology

Year 12 Heinemann Biology

will have to have a look and check to see if i still have the CD's for all of them. they are perfect for beginners. would prefer a trade for them but happy to sell also, im not after anything in particular so if you're interested make me an offer.
