Just ran into this site, was pretty useful for me and I just started studying. My math skills are definitely below par
But seems to have questions for all levels but I would say it is more geared toward the beginners. Also, right after you are done, you can check your score. Only downside is that there are no explanations for the answers but I guess you can always use this forum.
Scroll down to get to the sample questions. Hope this helps!
