As with most others, the toughest part by far was that 18 band EQ test. I probably spent 45 minutes or an hour on it. I ended up taking notes on what I heard with each frequency to make it through. Working from memory was just too tough for me.
I also had a little trouble with the artifacts, HFE, and reverb sections.
Loudness, bass, spacing, and noise sections were the easiest.
I realized that my hearing with the highs is definitely not what it used to be. I'm only 28 — I thought I still had a while before I had to deal with that, but I guess years of standing in the front row at concerts had to catch up sometime. It was a good time! Glad I got the opportunity to do it, and I feel I learned a little as well!
