GCSE Sciences 6 Markers HELP!

Hi, I am studying GCSE AQA Chemistry, Biology and Physics. I’m aiming for grade 9. However, I struggle with the 6 marker questions.

If anyone has a method or tips for how I could achieve (possibly) full marks for the 6 markers then please share them. Any help/guidance would be highly appreciated.

Thank you in advance.

One of my main pieces of advice would be to just state the obvious, even though you may think it is obvious the examiner may not be able to make those same connections as obviously. If the questions asks: compare ethane to ethane, for example, then you should firstly state that they are different in terms of structure, so ethane is an alkane so only has a single covalent C-C bond. Whereas ethane is an alkene so has a double covalent C=C bond. Then you’d build on this using their reactivities or if the question asks for anything specific
