Not sure if this question belongs here, but not sure where else to post it.

I'm doing a Physics essay for Uni (it's for the Access scheme, about the neutrino experiments) and I'm wondering what I need to reference.

If you use things like revision guides and classnotes and things to refresh your mind on concepts, and as general reading to help with the essay, do you have to outline those things/reference them in the bibliography? Do you add them as further reading? Or do A Level notes and things not count if it's just to refresh memory (eg on definitions of key terms etc) and you're not quoting or anything?

Thank you
