Hi,
I've finished the red books and gone through the advanced sections and solved the In Action problems. I feel though, I am still in need of more practice. I've tried the HW Banks, but these are too easy. I've done the Question Banks, and these were challenging, but there are only 25 questions for topic area. And when I retake, the questions repeat themselves. Also, I've looked at the challenge problems, but they're ordered by date, is there a way to look at these problems by topic?
I'd really like to work on some specific topic areas such as Absolute Values and Probability.
Thanks,
HoJoon
