TOK is essentially an extra class in addition to your core subjects. It’s kind of philosophy, kind of not- but the design of it is to make you think (in reality it just makes you confused). Really all you have to do is make a presentation and an essay and pass them. If you do there’s a potential for 3 extra points in combination with your EE. I hope that helps! And I promise- it gets clearer as you go along. Don’t worry about being confused for now.
