Programming I, II

This was the meat of everything that I learned and got me going with programming. These were the classes where you learned to program. Before I took these classes, I had barely even programmed at all. I had tried getting a head start but didn’t get much further than loops.

Discrete Structures in Computer Science

This class was added to the transcript to get people used to boolean logic. Which we had down in the first two weeks of the class. Unfortunately for us, unsuspecting students, it goes pretty far down the rabbit hole.

Data Structures

This class was good. Very good. Data structures are used all over computer programming and are the backbone of most of the code people write. They allow us to store data in a way that is useful to the programs we write. The ability to look at data and know the best way to store it for time and space performance is a very useful skill to have.

Analysis of Algorithms

This class was somewhat useful. Algorithms are useful. They drive the best software in the world and make them powerful enough to stay relevant in the modern world. But this class had some issues.

Web Development

This class had the most skills that were directly applicable to a job in tech. I learned about HTML, CSS, JQuery, JavaScript, PHP, and JSON. I learned how a request is sent from a website front end to a back end, how its processed on the back end and then sent back to the front end with a response.

Introduction to Databases

I mostly just learned SQL in this class. I am sure we went over some other concepts like sharding and clustering but I don’t remember them. I sometimes use SQL at my current job to run data queries for events I’ve logged. SQL is either going to be integral to your job or you will barely use it. If you need it, learn it and become an expert.

Software Engineering I, II

Also another class I can’t really remember. I believe we went over a bunch of broad concepts in this class. We covered Scrum and Waterfall project management methods. We went over testing and all the different types of testing there are. We covered some usability and accessibility concepts.
