LINCOLN, Neb. (AP) — Nebraska students have been scrambling to finish their GED testing, lest they have to start over again with new tests next year.

Vicki Bauer, of the Nebraska Department of Education, said “we’re just swamped with people trying to get their GED testing done.”

One earns a General Educational Development certificate by passing tests on reading, writing, social studies, science and math. Its high school equivalency is accepted by employers and universities.

The GED Testing Service will release a new series of tests in 2014, so test results on the current series won’t be valid.
