I’m a mechanical engineer and picked it up years ago as an alternative to cad duct/ fab (a better tool for install but harder to get used too in the consultant world) I’ve recently taught a senior AutoCAD guy in my office. He initially struggled coming from the cad world, due to the way you use it (he describes it as Lego compared to drawing) but picked it up pretty quickly as we got past the nasty bits of it. I would suggest you register for an Autodesk student account and download it at home and use it as much as possible in your own time. As the others have said above it’s really only practice and the most powerful parts of it (visibility etc.) will only really come to you once you’ve done some time. Just remember to get out on the bike between sessions, because it can be pretty addictive as you get better!
