i typed mine up, it did take a while, and I only put in what i needed, and got the school to print and bind it for me. ask your teachers, they should have similar facilities
however, typing math on microsoft can be extremely tedious.
An easier way is to organise your notebook by the study design. Split the book into even sections for different area of studies, then break those sections into separate pages for each key knowledge and key skill. and just add in whatever you need
But if you do want to type it up, remember to balance how much time you use on that vs other subjects, that is, dont waste time putting things on that you already know.
It'll be best if you could go over everything with your tutor/teacher prior to typing up to find out what you are confused with, what you find really hard, and what you can do with your eyes shut. Then write your notes accordingly.
but also remember that practice makes perfect, so do a lot of questions, you might not even need to use the notes.
