I'm taking IAS physics as a standalone subject as an independent candidate . i have revised units 1 and 2 , but unit 3 i have no notes for , and my school does not have a physics course , so there are no lab notes i can study. i need the notes for unit 3 on the core practicals , preferably with the results of the experiment and a risk assessment ( its ok if they aren't there , the method on its own would be good ).
