Simply put, what I used to LEARN everything was my CLASS, and my TEACHER.
There are students out there who prefer doing things themselves. They become more and more common at uni with people skipping lectures and stuff. However I like being taught exactly what I need to know. This reply may seem like a redundancy, but I am not even kidding. I sit down in class, listen/participate in the discussion, ask questions whenever necessary (most teachers didn't mind me interrupting them if I timed it right) and copied down whatever was on the board.
Then, as I was writing/listening, I'd process it all in. The teachers always told me what syllabus points were being addressed in today's lesson, and then I knew to tick off what we had done. And that was it.
Some students (such as the dux at my school) were motivated enough to reteach themselves the content at home. I didn't bother with any of that though.
Now, as for studying, a textbook is what you use to gather the information, not to read over and over. Whilst rarely they throw in something unnecessary, in general the language in a textbook should all be perfectly comprehensible to a capable student. If something does not make sense, then this needs to be addressed - ASK.
The textbook will tell you heaps of bits and pieces, but from your lessons in class and doing what the teacher said you know what it is that you require. You will also have some things engraved into your long term memory, and other things that you just wrote down and immediately forgot about. The things you tend to forget about are typically associated with some kind of drowsiness in class (laziness, fatigue, uninterested) or just not your cup of tea (roted content v.s. analytical/computational stuff such as calculations).
And then when you make your notes, you use the textbook as a reference, look at OTHER'S notes to have a GUIDELINE, and then make your own.
Also, typing is useful only in the formatting. Your notes can be edited any time you like, and they are always in a presentable manner. It is very difficult to top off the tidiness of typed up notes compared to hand-written notes, so the cost v.s. benefit is your's to weigh out.
P.S. I'm aware that there's a possibility I responded not with what you were aiming for. Let me know if there's more you want me to comment on.
