I honestly think they're cramming too much stuff in such a short time. Unless they're releasing those "20 hrs digital content" as .mp4 files for you to keep forever, I don't think you're going to absorb most of the info. Kinda surprised they don't have anything about web design (HTML, CSS) or scripting (cmd, Bash, Powershell). You're not going to get a whole lot out of Wk 3 because there's a difference between just watching some dude describe a development lifecycle and actually experiencing it yourself. It's one thing to read the Wikipedia article of Hofstadter's law, and it's another to experience it yourself. Wk 6-7 is going to either be the most useless weeks or most valuable weeks, and all that hinges on how well you can network with potential employers.

I think it's better if you do some studying on your own before taking the course so you won't be completely lost when you actually take the course. There's plenty of online resources like W3School to get you up to speed on basic stuff. I don't know your technical background, but there's great value in reading code that other people wrote. You don't have to understand everything, but the gears in your head should start to turn. You can also get your feet wet with some home projects. Try writing a batch file or setting up a web server.

Lately, I have been playing around with ADB. I'm not an app developer, but one immediate use of ADB is I can uninstall bloatware on my Android phone without rooting it. Maybe this can be your project. Set up ADB on your PC and use it to uninstall useless junk on your Android phone.
