I'd say fairly easy, especially if you're not working full-time. It was difficult for me because I have ADHD and that makes the extra focus necessary for accelerated learning difficult, but if you're good at focusing and driving yourself to finish things quickly, I've seen people get WGU's CS degree in as little as 1-1.5 years.

I'd recommend checking out the various subreddits dedicated to WGU, their college of IT, and the SWDev and CS programs (r/wgu, r/wguit, r/wgu_devs, r/wgu_compsci). There are also student-run chat servers on both Slack and Discord.
