The College Board has made the decision to redesign the SAT to a completely different format than ever before.

Just about everything has changed with the new test. Scoring now begins with 400 and goes to 1600, instead of 2400 as it did previously. The test is available electronically and also includes optional sub scoring and cross-test scores.

According to collegeboard.com, the first section is no longer critical reading, but is called evidence-based reading and writing with a 65-minute reading section and then 35-minute writing and language section. There is no longer any sentence completion questions. They now focus on multiple-meaning words. Reading passages will draw from significant historical or scientific documents including informational graphics, such as charts. They also will include complex structure and vocabulary.

The math section is now divided into a 25-minute no calculator section and a 55-minute calculator section. The questions are more application based and require critical thinking to solve. They build a deeper understanding of the theories behind mathematical principles according to princetonreview.com.

The essay is optional and is 50 minutes long. Students will be provided with a passage and will analyze the author’s argument. In order to do so, students must be able to understand literary techniques used by authors.

With the new test, content, format, and scoring of the test has changed to prioritize content that reflects the type of information students will encounter in college and in their future lives.

Collegeboard.com also stated that this change is the biggest in 30 years and will begin on the March 5 test this year and will begin to impact students in the class of 2017.
