See this would work, but a lot of my classes make it so you have to take notes from the textbook before class. So the 2 notebook thing wouldnt work for that.
With the time you take to copy on the other notebook, you could read entire manuals and forge yourself a good culture on the subject... My method consists in writing everything down, including the teacher's jokes and disturbances, and adding personal notes in the margin (or when I take notes on my computer, memes that feel somehow relatable or connected to the subject). This way, my notes feel less boring and I memorize them more easily. They aren't super clean and a cat wouldn't find their kittens in them, but I made them so they're clear to me. I only read them briefly just at the beginning of the following lesson and before the finals, and bam! Good grades and free time.
Since you have finals coming up
