I did it last year. I don't think you need to know anything for chem practicals.
Oh you have to know how to build tables, because they give marks on that
even if your readings weren't correct. You can take a look at the marking schemes
of past papers and see the distribution of the marks.

Follow the instructions carefully, keep in mind that you have 2 hours only, and
don't panic. That's all I could say. Good luck =).
