Hi @Krystal_Biggs, welcome to the forums (and to Premium)!
You’re right, that’s pretty frustrating. At the moment we offer book downloads (as you would have seen) but course downloads are still inelegant. It’s one of the project we’re working on.
We’ve also had a few requests for making our screencasts downloadable. Would that be helpful? Screencasts don’t have PDFs and code samples, as courses do, so they are simpler to download and store.
