College entrance exams (SAT and ACT) are used by universities to assess your readiness for college-level curriculum. Some universities require a score within a specific range, and some do not. We recommend that students take both the SAT and ACT to determine which exam is the best indicator of their knowledge and ability.
The SAT exam is usually taken for the first time in your junior year - Spring or Winter. The SAT will require you to think critically and assesses your aptitude for reading, writing and mathematics. Click on the link and register through College Board; the SAT is held at CDO.
The ACT exam is usually taken for the first time in your junior year - Spring or Winter. The ACT assesses your knowledge of the content you have taken in high school - English, mathematics, reading and science.
The PSAT is the practice exam for the SAT. Some students take it twice - fall of sophomore year and again in the fall of junior year; junior year scores are used to determine who is a semi-finalist for the National Merit Scholarships.
Online resources are available to help you practice for college exams. Check the exam sites, or other sites, like Khan Academy, that offer such practice at no cost.
