I am currently doing this bootcamp alongside FCC. I made 50% so far and I feel really good with what I’m learning. Basically, I watch the videos, try myself every code and after that I do the FCC exercises. This strategy is working really well for me. The best part is I paid just 7 dollars on the web dev bootcamp (I live in Brazil).
Ps I agree you can find awesome free content around the web, but Colt structures the course in a really solid way, which can for sure bring a more accurate learning.
