Hey...did any of your teachers provide you with any questions/exercies for this article just for practicing? If yes, please do share...and Thanks buddy for sharing the article...
I also want to know that if you can access the confidential article on the edexcel site, can you also access the examiner reports for biology june 2010 U4, U5, U6b on the edexcel site (because they appear to be confidential)? i already have the jan 2010 U4 and jan 2011 U4, U5 and U6b examiner reports but need the jun 2010 examner reports and thank you once again
