What if I have already taken a mock SAT or ACT?
If a student has taken a full-length real mock ACT or SAT at school or with another tutoring company, we are happy to interpret those results. Real scores are always great as well!
Be aware: “Mini-ACT” and “SAT/ACT combo tests” are not the same as a real full-length mock test. They are typically an abbreviated marketing tool with fake questions that are very inaccurate and waste students’ time and may lead the student to choose the entirely wrong test!
Is the PSAT the same as a full-length mock SAT?
The PSAT is the exact same length and number of questions as the real SAT and is an acceptable proxy for students who are deciding between SAT and ACT. About 70% of our students compare their most recent PSAT score to a full-length mock ACT to make the SAT vs. ACT decision.
One exception: If a student had a very high PSAT score, it’s likely advisable to take a mock SAT. If a student has a most recent PSAT of 1380+ and has the free time, it’s well worth taking a mock SAT as well as an additional data point since there can be more variability and volatility at the very top end with the reduced number of questions (90 on PSAT/SAT vs. 215 on ACT).
ACT vs. SAT: Which test is right for me?
The best way to figure out which test is best for you is to do a diagnostic test for both tests (or compare a PSAT to a mock ACT) prior to significant study to see which test you are naturally better at. In our experience, about 10% of students perform approximately the same on the SAT and ACT, with about 45% performing meaningfully better on the SAT and 45% performing meaningfully better on the ACT. Do not rely on old rules of thumb from teachers or friends to decide which test to take; simply take a diagnostic on each and then focus on your naturally stronger test! The only tests that should be utilized when taking these diagnostics are actual SATs and ACTs.
When is the best time to schedule a mock test to ensure class availability and time to study?
Taking a mock early on is wise, since most students study for 6-12 weeks for the tests and since group classes and the private tutoring calendar fill on a first-come, first-served basis. Our private tutoring calendar often fills 3-5+ weeks out (especially weekends), and usually, all but 3 or 4 of our group classes fill each year.
