Unless you are scoring in the high 600s or higher on your PSAT and are interested in qualifying for National Merit (you will get this year's test results early next year from your school counselor), then we advise a baseline mock test after you complete your sophomore year. From the baseline mock test results, we will recommend what you should do to prepare for your first SAT and/or ACT. We advise juniors to complete at least two SATs or two ACTs.
