As many of you know, I use a website called Biology Corner for some of my material. A new feature has appeared on this website that A level students may wish to try out for revision. There is now a series of interactive self-marking quizes covering a variety of topics. The address is www.biologycorner.com and along the top menu bar there is a category marked quiz(es). The only point to bear in mind is that the site is American, run by a biology teacher in the US. It is, therefore, not the UK syllabus nor the UK spelling! But still a good site to use.

A2 students should try respiration and photosynthesis! I scored 100% and 80% respectively. Can you do better?
