Trying to be semi-productive despite being unemployed as of recent, and spending time learning new technical stuff. I've been working through the beginner programming course on the MIT OCW site, but I was also trying to see if anyone could recommend something for learning specific software for work usage, at the moment mainly QuickBooks and PowerPoint.
I found a bunch of things via Google but a lot of them look kinda shady and I was hoping someone might know somewhere reputable that I can check out.
