The echo boards this year (2025) weren't bad; they were pretty fair, to be honest. I took it in 2021 while still a fellow and failed it; I hope I pass this time around. I did notice that the interface looks much cleaner, more modern, and the updated scientific calculator - I LOVED IT. We can finally square stuff and see what we're doing with our equations.
The third block was the hardest for me, and I almost run out of time. The physics portion of the exam was the most challenging, and they didn't require many physics calculations; instead, they focused on asking about concepts. So that was hard. However, I think it was a very fair exam overall.
Only time will tell if I passed. I hope I did because I studied HARD for this, and I need it for my job.
