This site will prepare any student for the math portion of the SAT. It greatly improves skill, confidence and comprehension of math problems regardless of type and level of difficulty. It helps identify one?s areas of weakness and target them in practice. Its option of trying the problem again, with different numbers, forces one to understand and learn the process of solving a particular type of questions, versus giving up and never improving. The timer allows you to notice which types of problems give you the most difficulty, as do the category and level of difficulty indicators. This site is effective, well organized, and easy to use. I would recommend it to all high school students.
