Worried about taking the new SATs? For the first time, Kaplan Test Prep is holding a free, all-day, live online SAT prep event from 11 a.m. to 11 p.m. on Feb. 21 to help students prepare for the new college admissions test that launches on March 5.

This event will feature instruction from some of Kaplan’s most highly rated teachers, who combined have taught about 24,000 students. Participants can ask questions through Twitter, using the hashtag #SATPrepathon, and can also interact through live polling.

“Given the heightened anxiety brought on by a new, redesigned SAT, we wanted to create a free all-day forum that allows all students, everywhere, the opportunity for live engagement with top instructors and fellow test preppers,” Lee Weiss, vice president of college admissions programs, Kaplan Test Prep, said in a news release.

“While the Prepathon is not a substitute for comprehensive studying, it will give attendees the opportunity to hone their skills further and build up confidence for test day. It will demystify some of the new SAT’s most difficult question types and help students looking to earn every point they can on the exam,” he said. “This SAT will see its biggest changes ever. While changes like eliminating the wrong answer penalty and obscure vocabulary will help students, other changes like limiting calculator use and adding deeper and more rigorous content will lead to a more challenging test experience overall.”

At every hour, on the hour, a new segment on a new topic on the SAT’s Reading, Math and Writing section will commence. The 12-hour open format is designed to allow students to come and go as needed, and stay for whatever amount of time they feel is valuable for them.

No registration for the event is required. All students need to do is log on to kaptest.com/prepathon at any time during the event.
