Hello! I'm new here, and I need some help with revision for my mocks (and eventually, proper exams in June). Basically, I usually start with the spec from the exam board, and then use my own notes, the textbook and the internet to make flashcards and then test myself using that. But with quite a few of my subjects, such as Physics, I've found that my notes and the textbook are an awful lot more detailed than the spec is.
For example, on radio waves the spec says this:
2.2a) ...Candidates should know the order of electromagnetic waves within the spectrum, in terms of energy, frequency and wavelength...
b) Radio waves, microwaves, infrared and visible light can be used for communication.
2.2c) Electromagnetic waves have many uses for example:
- Radio waves: television and radio (including bluetooth)
But my textbook and notes go into loads of detail, talking about frequency bands, diffraction, transmitters, receivers, diffraction, why they're good for transmitting TV/Radio/International Radio, interference, the ionosphere, the actual wavelengths and frequencies, Bluetooth etc.
So what should I learn? The whole textbook seems a bit excessive, especially compared to the spec but at the same time I don't want to be under-prepared.
Thanks in advance

In terms of comprehension, I get that you have to understand and be able to apply pretty much everything- but in terms of hard facts if you go by the spec using the textbook to 'flesh it out', would that be enough?
