Suggestions for Kwizzes

What other kinds of quizzes would you like to see on this site? One issue that I have encountered in the 'self-test' quizzes is that I can lazily rely on getting the answer by knowing that I'm going to get a question on a recent grammar point, etc, which means I'm not really thinking with any great depth, only assuming that the answer will be in reference to a recent lesson. For example, if I've just learned that por can refer to 'approximate location' I will know that that is going to be the answer when I encounter that kind of question (which might be amongst several conjugation type questions so will be even more obvious). I think the best way to address this is for the site to offer more general thematic quizzes to help consolidate certain points. For example, there could be a quiz on Por v Para which you could take after Stage A2. I would add these to the library as 'Consolidation Exercises'. Unfortunately, I think that our brains will always take the easiest route to the answer which isn't always the best way to learn.
