Biology Mock exams?

[Jerusha A]

I have a big end of year exam in two months, i'm worried about
biology. Gcse biology.
The teacher said there would be photosynthesis, Respiration,
Muscles,(Antagonistic), in the test.
Last time i took this exam(this is my new school), i was told
by the teacher to only study by textbook, and i was worried
because the textbook contained too few information, and
the result was as i thought,///very low grade.
So this time, i'm thinking i shouldn't really rely on the textbook.
I'm also looking at bbc.co.uk to help me.
Does anyone know where i can get practice exam papers
online for biology on (photosynthesis, respiration) topics?
Like practice test paper questions that are really likely
to come in the test? 'cause my school biology exams
kind of twist the questions, i won't be able to get high
marks just by looking at the basci info on the textbook.
please help me !
