I'm a junior in high school and I have just completed 100 problems from XLMath in the 'my quizzes' section. I took the PSATs one week ago after I had answered about 50 questions from XLMath. I found the site helpful because it helped me realize how much time should be spent on each problem. XLMath is a clear and professional website. Some parts that I like are the timer and the quick answer to the problem. The step by step answers helped me with problems I didn't know how to do.
