Taking practice SAT/ACT tests is one way to prepare for official test dates and can help students decide which test may be right for them. Full-length practice tests are available for self-proctoring at any time through the College Board and ACT. Revolution Prep will also offer a free online proctored SAT and ACT test for Deerfield students on Sunday, Sept 22. Interested students can register here. Other dates are also available; contact Vasilios Kostakis.
