There are some private torrent trackers that have them. I got a 2020 site rip from Speed(dot)cd. TheGeeks is a tracker specializing in educational material, but I am not in it. Both are accessible through MAM but TheGeeks is a little harder to get in.
I could temporarily share what I have through a OneDrive link, it has 96 courses, ~400GB.
Sure, I’ll send you pm and you can download it all or just what you want.
All the best with the exam and taking care of your family!
