I took a very similar class 9 years ago, and it was honestly one of the most helpful things I got out of my CS degree. The low level and limited tooling taught me to think before I start writing.

I've had other people look askanse at me, but on greenfield work I tend to start with pen and graph paper. I'm not even writing pseudocode, but diagramming a loose graph with potential functions or classes and arrows interconnecting them. Obviously this can be taken too far, full waterfall planning will be a different exercise in frustration.

I find spending a few hours planning out ahead of time before opening an editor saves me tons of time actually coding. I've never had a project even loosely resemble the paper diagram, but the exercise of thinking through the general structure ahead of time makes me way more productive when it comes time to start writing code. I've tried diagramming and scaffolding in my editor, but then I end up actually writing code instead of big picture diagramming. Writing it on paper where I know I'll have to retype everything anyway removes the distractions of what method to use or what to name a variable.

The few times I've vibe-coded something this was super helpful, since then I can give much more concrete and focused prompts.
