OP- you are describing attending college part-time, taking one or two classes per semester, and working to figure out what you’re interested in and where you want to focus.
Nothing wrong with that- some of the most talented people take college “low and slow”.
It is unrealistic to think you can take a full academic load and not feel time pressure to complete assignments, or have the luxury of doing things at your own pace. Again- nothing wrong with your personal learning style, but you need to understand how an academic calendar operates- semester starts, semester ends, and a lot of learning gets stuffed into those bookends.
Why not finish off the semester, take a leave, get a job, and then find a college where you can take classes at a more leisurely pace which is also affordable?
And understand- the core/foundational classes in ANY discipline are going to be focused on the basics. Could you play a Beethoven Sonata without having spent years doing scales and practicing to develop your finger strength? That’s what college is like. The first year or two you are doing scales in order to get to the complicated stuff down the road!
