WASHINGTON (AP) — Creators of the Common Application for college admissions said Friday they have made changes that should prevent snags that had the high school class of 2014 tweeting horror stories.

The Common Application is accepted by more than 500 colleges and universities and allows students to apply to multiple schools at once, but it had a rough applications season after new technology was rolled out last year that created many headaches. About 750,000 students submitted 3.3 million applications last year.
