I hadn't heard of advent of code, I'll be sure to check it out. I definitely agree that the "bootcamp" courses tend to be more for reference, but they don't advertise as such and so are misleading. Some of the ones I've purchased are made by people who say they have taught actual bootcamps, so I was expecting more of a school/college type of experience with extra practice. The last few courses I've purchased (minus the Java one I'm really happy about) ive returned.
