Unfortunately, I hit a roadblock while implementing the Raft assignment. I knew it was simply beyond my capabilities but would have made through if I had anyone I could reach out to. I second this recommendation, but make sure you know what you are signing up for. This course is as hard as they come.
I have found the performance tests very tricky to get to pass without having any input from others. The assignment is really very unforgiving, I would wager the test suite is comparable to how commercial Raft implementations are tested (e.g. https://github.com/hashicorp/raft)
