First Class Pilot Exam - Great Lakes

Hi, I recently switched from Deep Sea to Great Lakes for shorter rotations, and to be closer to my kids. I have a 2nd Mate Unlimited, and I am working on getting my FCP, but have had a really hard time trying to get study material. I’ve contacted the USCG, GLMA, and harassed many of my shipboard colleagues trying to get study material, but to no avail. Does anyone have a good contact for GLMA that I could get some study material from, or have it themselves and are willing to share?
