Northwestern resumed pre-registration for students with senior standing at 4:30 p.m. Tuesday after shutting down the course management system Monday afternoon.

“We got a fix into the system, so we’re back in business,” said Suzanne Anderson, the university registrar. “The rest should just progress normally.”

Pre-registration times for students with junior, sophomore and freshman standing were pushed back to adjust for CAESAR’s down time and now will end at 4 p.m. Thursday.

Students with declared majors experienced problems with CAESAR due to a system upgrade over the weekend, Anderson said.

Some students were unable to register for classes they needed, and others were able to register for classes that should not have been open to pre-registration. The latter students were notified that the university had dropped them from those classes.

“(CAESAR) did a variety of things wrong, and that’s why we said, ‘We’ve got to stop,'” Anderson said.

Anderson said students responded well to e-mails from her office and from academic departments with updates about the system.

Weinberg senior Jessica Jackson, who received an error message Monday when she attempted to register for political science classes at her designated time, said she had no problems Tuesday.

“Everything was fine for me when I got back from class at 11,” she said.

CAESAR’s problems were more of an inconvenience than something to get upset about, said Naveen Malik, a Communication sophomore.

“I just declared my major, so it did affect me a little because it was the first time I had to pre-register,” she said. “I didn’t know what was going on.”
