@TooFriendly112,
My wife and both our adult children are all PhD's: Psychology, Sociology and Mathematical Physics respectively.
Yes, take contemporaneous notes ... but do not miss information because you are too busy taking notes: These days recording the information is a good idea - Ask permission first.
The other suggestion which my wife and both children still do as PhD's is have a spread sheet of all the books they read and/or the books they reference ... Then date them, publisher, ISBN and what you used in your own work. This is so that when it comes to your own work and literary revues in that, you know quickly when and where that information came from.
I have no idea what you are doing, a BA or BSc maybe but take a little general advice .... Bachelor degree work (especially) is marked via a 'marking grid' ... Ask for one of them from your course moderator, so that you understand how and what they are marking.
Also understand that all work is passed through a computer programme that checks for 'plagiarism' and it is extremely accurate. It is almost impossible to produce work that does not bring up some result on this system ... But any more than a reading of c.20% will certainly trigger an in depth investigation of you and your work.
Good fortune to you, enjoy the learning experience.
