So I don't know how I'm gonna combine textbook info and lecture info into my notes without it taking insanely long. I wanna record lectures as they happen, then relisten in my own time whilst making notes. Ideally I'd then combine the lecture notes with any extra info in the book in the form of mind maps. Now this will take too long so how do u guys manage your time?
Learn how to take notes in class. In some classes (e.g. math) it makes sense to take very detailed notes. In other classes, you might only need to jot down the key points and a few interesting thoughts that come up (leads for papers!). Find out what works for you.
Also figure out how to work with your textbooks. Some textbooks are best used as a reference but you really shouldn't try to read the whole thing. In some courses the text is best read before class; in other courses it's best read after class. Decide if you should work with highlighters or stickies. I like to mark quotable passages in my social science or humanities readings. Knowing where to find the key quotes makes my life SO MUCH EASIER when I have to write papers that work with several hundred pages of material.
If anything, use the recordings as backup if your mind wanders during lecture and you missed something. There's no reason the vast majority of note taking can't be done during lecture. You can highlight parts of your books for quicker reference later and write down a few thoughts in the margins, to use for papers or discussion. You don't need to "combine" them by rewriting what's in the books. Simple highlighting and a few flashcards should do.
Take good notes in class. A lot of times, the tests will be based mostly on these notes. But for my personal research notes, I make another page labeled "Reading Notes" and then the book and page numbers and then I do bullet points so that they are easy to be related with the class notes.
Don't try to do the recording of lectures thing. It leads to not paying attention in class closely enough and then a ton of additional time listening to the tapes and retaking notes. I tried it when I was in college in the 80s. When I went back for a second bachelor's in the 00s I'd learned my lesson!
