No problem! For maths, find as many practice questions as you can and don't get discouraged if you get a question wrong in a topic you feel confident in, just copy down the steps in the mark scheme and remember for the future!
So for science and rs for example, these are subjects with a lot of content, so it helps me break down each topic when using the spec (as the spec gives every single point that we would need to know).
Here's an example:
The biology spec for aqa in the topic of infection and response says this:
"Students should be able to explain how vaccination will prevent illness in an individual, and how the spread of pathogens can be reduced by immunising a large proportion of the population."
"Students do not need to know details of vaccination schedules and side effects associated with specific vaccines."
In those few lines on the sub-topic of vaccination, it tells us what we need to know and what we won't be questioned on. I summarised that point and wrote this down as my notes for the sub-topic of vaccination:
- Vaccination - small quantities of dead or inactive forms of the pathogen is injected into the body; this stimulates lymphocyte production and makes antibodies to destroy these pathogens; if the pathogen enters the body again, the memory cells would quickly make the correct antibodies to defend against the pathogens
So I only used the specification and freesciencelessons to make my notes.
I'm not in Y11 yet! But my main tip is to revise as you go along - I find that just relying on what the teachers teach at school isn't enough, so just take one or two hours a week to start off with to make your flashcards for subjects that have a lot of content.
