Engineering notepad is what I used in school. You may want to keep it in a folio to prevent damage to the corners and top page(s).
Slightly off-topic: Regular graph paper like you used sucks. The heavy grid lines interfere too much. Check out engineering paper; once you try it you'll never go back. It's basically graph paper, usually yellow-green in color, except the grid lines are only on the back. The grid lines are still faintly visible on the front so you can use them as a drawing aid, but they don't have the visual clutter that would be a problem with normal graph paper. Also, if you scan it, the grid lines disappear. The grid squares are also smaller (1/5" instead of 1/4"), more suitable for construction drawings.
Here's a link: https://www.amazon.ca/dp/B001J87JTM. It's a bit expensive but I don't use much so to me it's totally worth it.
I got through engineering courses in college using standard notebooks for note-taking and using these for homework problems.
It's super easy to use in terms of staying neat and organized (both great skills to hone at school) and I personally liked how easy it was to tear sheets out and turn them in (versus grudgingly ripping out the frilly mess on some spiral notebooks).
Definitely not knocking the tablet route, I just enjoyed the old-school method the best. Good luck at school btw!
I used these guys. Just pop them is a binder and go. At $7 my student budget approves.
TOPS Engineering Computation Pad, 8-1/2" x 11", Glue Top, 5 x 5 Graph Rule on Back, Green Tint Paper, 3-Hole Punched, 100 Sheets is all I ever use. I use them for notes, sketches, even tracking HP when I'm DMing in my D&D campaign...
I also pasted this link in your other posting:
I hope it's what you're looking for.
I use this one
I've always liked green engineering paper a lot but it doesn't really matter; you do you.
This stuff. Never left home without it in college.
