@mgage If you'd like to assign some of these to me, I'd be happy to take a look.

Could you look at #290 an #284 in pg? Make sure the PR starts from the develop branch.

Could someone who uses Gateway quizzes regularly look at #740? I think the issues are largely fixed but we need better documentation on Gateway quizzes to try to reduce the number of times the same questions are asked about the Gateway quiz options.
