Please help me. There is one thread but no one has replied. Has anyone done it, and if so could you help me with what to revise for the test part, I've already done the practical.

Thank you so much

Yes, I've done it! I think that's the one which smells bad! Just revise ISA keywords (particually variables and callibration) and graphs/results. To make the experiment more precise use a pipette. You can apply this knowledge to both parts of the exam. Remember, some questions are general knowledge, for example, what do you look for when buying a washing machine. Good luck!

i did the exam on wednesday,, its ok you need to know what calibration is, it does ask about errors, the last q (5marks) asks you to desgin an investigation about 2 washing machines and how to work out which one is better (using equipment shown in first experiement: light meter in water in washing machin), the last last q asks what do you look for when buying a washing machine except for how well it cleans your clothings? .... ummm.. the rest are easy, like one i think says did you have any errors (yes/no) explain why? ummm... also in section 1 it asks how did you come to your conclusion (previous q what was your conclusion) show this from your results. I think thats it the rest is fine.
