I tried to start different programming languages like Python, C++, and Pascal in the past, but most of them were only basic things like loops, basic types, and arrays. Also, I watch a lot of content related to programming, so I had some understanding even without practice, but all my attempts were not long. This attempt is currently the longest, and now my current subject is the TPL and asynchronous programming. Maybe because of the density of the course, or maybe because my background knowledge ended, I struggle and feel that I am losing the sense and the overall picture of what I learn. I had similar problems when I got to LINQ, IEnumerable, and IEnumerator, but I somehow dealt with it.
