I am looking for any advice, we use Nelson Thornes e-science at my school and have the text books as well. I also have a copy of biology for you text book at revision guide. Does anyone know of any good AQA Biology software, CD-roms, revision material to back up the Nelson Thornes stuff. I have had a look at the CRG books today which looks good in terms of questions. Any suggestions would be gratefully received!
