Up to 12,000 students scheduled to take the ACT on Saturday could be affected by a massive winter storm that's expected to engulf much of the Northeast this weekend.

Approximately 80 test sites out of 190 in the region have canceled ahead of the storm, Ed Colby, a spokesman for the tests, told CNN.

Each site will reschedule the test, and students and parents can get information at http://www.actstudent.org/.
