I'm with all of you on the quizes. They should let us know what is missed so, we know exactly what to focus on. Our time is valuable, too. And we go through all of this so we can qualify for a shop, only to come back home and spend however long it takes to enter and meet their demands in the computer.
I've been lucky on the GFK quizzes, but I also found that certain areas use Kern as their schedulers and those work much better for me, as I can work direct with them.
I too, was receiving bunches of their emails and I just got to where I wasn't responding to them at all and now they've slowed down to a normal pace. They must have had some glitch somewhere. Wish they would all have a direct link to click on from the particular email. That sure makes it easier to reach the site quickly and see what's there.
