It is annoying to be returned all the way. But if you're quick clicking your browser buttons, then after you've rated the quiz - while the screen says "Now returning you to where you were" - you can press "Stop" and then click Back at your leisure. (I think you need four Back's: once to get to the answers page, once to the questions, once to the summary, and once to the category page.) Yes, it's annoying, but if you were going to click "Back" anyway it's only an extra click or two.
