How to answer Unit 1 electricity 6 markers (usually involving a circuit)?

These are the questions I'll drop almost all of the marks on, and the follow up questions marks. I can't seem to find revision videos online at all for this type of question.

Examples: June 14 - Q.5) --- Jan 13 - Q.5)

what exam board are you?

Reference how you record temp, vlotage current ect, how you vary factors (i.e water bath/ice for thermistor).
How many repaets/ recordings you take, what you plot on a grpah and what it shows/what gradient and y intercept are and possibly safety procedures if it asks for them

Nice, is this the sort of thing you would write for every 6 marker on circuits?
