This evening I ran back over my old assignments from my first attempt at Advanced C++ (CSC234) been rereading the original lab I got stuck on that forced the withdraw (well… that lab and the OTHER 18 credit hours [21 total] I was taking at the time). It was a fairly simple lab, just play with some bank tellers, some customers and a few timers, that’s it. A simple, straight forward modeling program. Unfortunately, the lab still scares me and my own original source code makes no sense. I am likely to take a whole different approach to that lab (or whatever has replaced it now) when the course opens, especially having my knowledge of data structures and things now. I feel more prepared than ever to tackle these labs now, mostly because I don’t intend to waste time with things and procrastinate before getting them done, so I will have plenty of time to research, get help, etc. I have thought about this course too many semesters to let it get away now. My self-esteem needs to take and pass this course (honestly, I need an A…I have only gotten one non-A at CPCC and it kills me).

Anyway… whatever I do this semester has to be better than this:
