Boys avoiding Biology

I teach Chemistry and Biology. I despair at the fact that Biology is now little more than a science themed humanities course. The apocalypse in Biology happened in 2004, when we were the first science to get the crazy new “no marks allowed system”. We are limited to 1 test per year, and students get their final grade mostly from assignments and EEIs. A student can get a VHA with almost no transferable knowledge of Biological concepts. Compared to 10 years ago I now teach a class of girls, and I don’t blame the boys from avoiding the subject. How many boys are we driving away from careers in Biological research, because the high school subject we teach has become ridiculous?
