G482 exam tips?Watch
I'm retaking the exam to try and boost my A2 score, and over the two years, the best thing I have learnt about the OCR B course it to hammer out past papers, and know the definitions and equations well.
Also, the units. They used to annoy me so much, but if you take a little time to understand what the units represent, you can get good marks in the first section of the paper.
Be very aware of the powers, as they try and trick you, and match the number of significant figures to values given to you in your answer by rounding appropriately.
Make sure you have prepared for the advance notice article by answering questions on the material and trying to guess what they might ask you as it is a large part of the paper (40/100).
Hope I have helped, Good luck~
