When it comes to test prep, earlier is better than later! Despite that every student is different, we generally believe that beginning test prep at the start of your tenth grade year is the best way to go. That way, you can benefit from a full year of learning and practice tests and still have plenty of time to take the real deal.
Some students feel more comfortable starting test prep during their freshman year, while others start at the inception of their junior year. In the end, what matters most is that you create a schedule that works best for you.
