Computing courses in University fit for my current 'track'

First off, it's great to see you have such a desire to continue learning what you're learning. That's a great sign.

I want to address the differences between Information Systems (IT) and Computer Science (CS). In IT, you use programs to solve business processes. One such example is setting up a network between all employee computers. In CS, you make the programs that are used by others. One such example is creating a website with HTML and CSS that uses Javascript to run (or GET.. hehe) PHP files on a server that returns information from a database. (Quick note: This is only a general idea of each field and both are much, Much, MUCH deeper and richer than this).

If you're interested in the programming side of things, I would recommend looking in the direction of Computer Science. There you'll not only learn how to code, but best practices for coding, how to work on a program with others, and much more related to the creation of software.

Now, you mentioned that you want to go into the business/commercial side of the industry. In that case, I would consider looking at either IT or CS majors(depending on your interest) as well as a Business major or minor. Having that background in business will put you one step ahead of the CS majors that have a great concept, but no idea how to actually make it thrive commercially.

Overall, you've got a lot of research to do :) You would be doing yourself a favor if you could state exactly what you wanted to do in a sentence or two. If you can do that, then you have a good idea of what your path looks like. To get there, I would recommend looking at job postings from all over (All the way from Google job postings to your local grocery store that is looking for someone to make a website for them) and seeing which jobs interest you ("HEY! I would LOVE to do that for a living!!"). Then look at the requirements/experience needed for the job. Then start researching those requirements and seeing which way that points you.
