In a first, Georgia, U.S. students will take the SAT entirely online (no pencils required)

The largest college entrance test in the US, the SAT, is going digital.

The SAT, a college admissions exam that for nearly a century was completed using paper and pencil, is now officially all-digital.

This week, students in the U.S. will begin taking the new SAT on their own devices — including a tablet or a laptop — or on school devices. The test is also one hour shorter (down from three hours), has shorter reading passages and uses digital tools, like a highlighter, a graphing calculator and a bookmark to go back to skipped questions.

The revamped test, which ditches the paper and pencil, aims to make cheating harder and grading easier.
