atomic mass - decimal places

Im currently doing GCSE chemistry and I'm wondering to how many decimal places do I have to know the atomic masses of the elements at a level, or do i need to know them at all (i only know the whole number value at the moment), also any other tips for a level chemistry would be useful, thanks

You don't need to know them at all! You should get a formula sheet with the periodic table in the exam

Oh really, thats great (i've been learning them but oh well), is that for all exam boards, which exam board are you with?

Sorry for this super late reply, I haven't been on lately :P

And I am doing AQA A level at the moment (new spec) (:

It should be the same over all exam boards but sometimes it's useful to know common ones, so that you can do calculations without having to check the periodic table (e.g. carbon is 12, oxygen is 16) etc
