Don't worry, it isnt that important but paper 1's past papers are. Look, just go through them and it doesnt really matter unless you've read the book thoroughly and know the concepts. The paper is unseen anyways so focus on revising. Do solve a few papers tho, there's still time

I have a question for you.

Q) Describe how the excretory products of the body are excreted?

(excretory include co2, nitrogenous waste, excess water, bile pigments)
I created this myself so don't freak out if its not part of syllabus.
