A level Biology: Post your doubts here!

First tell us what does this mean :
'At least two readings for each solution'.

I don't see what readings you have to take. You just have to write the colors. :s

I should tell you?
I was hoping that you could interpret that mark scheme for me!
That's why I posted!

Meh. What do I care? If I do everything else right, I'll still get the 6 marks.

Well i guess that wikibooks are quite unreliable coz they can be edited if you are logged in. Do you have any other suggestions?
Anyways, thanks for helping me.
