The only reason we ask you to enroll,
rather than making the site generally available, is that this allows us
to personalize your tutorial. Once you enroll, the computer keeps
track of your strengths and weaknesses and the material that you've
covered so far. Unlike other test prep sites, which might have a
complicated registration process with a long diagnostic test, on Number2.com you can jump
right in and get started. This is because our site continuously adapts
to your ability as you go along. As you work through a set of practice
questions, the computer selects questions that are tailored to your
ability level in each category. That way, users of all abilities will
get challenging but doable questions.
