the bio xam waz da easiest xam eva except 4 da blood cloting Q it waz 2222  hard     ....and very long .....about the dry mass u can't substract the final mass from the initial masscuz the initial mass may contain some water so it's not the dry mass

[IG-Girl09]

I think it was ok, but ya compared to last years it was hard and very long ! I kinda needed 10 more minutes just to go through my answers.
I was a bit stuck in question 4, the one about plant nutrition. And about the dry mass question, you have to kill the plant to get the dry mass, so you can make sure that no water is in the plant.

the paper wasnt that hard, in fact, it was one of the easiest i solved and it was easier than 2008............its was very long though
