Orientation: My orientation took like 2 hours (if that). It was pretty simple. Mostly a "Make sure you can stick to a plan" stuff.

Webcam: I got mine on Amazon. I'm happy with it, but I had an identical one at work already so I knew what I was getting. I tried a Microsoft Lifecam before, but it doesn't have a focusing feature, so I had issues trying to get my ID to be legible with it.

Starting Tips: Not really, I had done lots of research. I'll say that having an 'office space' set up is a godsend. Make sure there's nothing on the walls, clean desk, that sort of thing. It just makes the whole online proctoring procedure go quicker. It's also important that EVERYONE else in the house is aware of what you're doing, and leaves you alone during testing. A closed door MEANS leave you alone. Make sure you're asking them "Hey, I need to take a 90 minute test, what time works for you?" so that you're not angering them. That sort of thing.

Acceleration: Just keep at it! Time input is directly related to course completion. I'm 2 1/2 months into the program and have 8 classes completed (not including the orientation). I'll spend 12 hours a day on the weekends though, and as much time during the week as I can manage. If you get stuck, google it. There are TONS of course reviews here on reddit that are super helpful for what to expect. Make sure your mentor is available and is keeping one step ahead of you. They should always have your next course cued up in your degree plan so you can start it as soon as you finish your previous one. If they're not keeping up, ask for another mentor. It's your time/money that gets wasted if they're not on the ball.
