Regular system maintenance
We are committed to the continuous improvement and optimized performance of our online study tools for our customers around the world. Periodically, we need to perform system maintenance which may interrupt your access to the online program for a short period of time. When required, this will occur on Friday mornings between 12:00 – 4:00 a.m. Central Daylight Time (GMT-5). Please plan accordingly. Thank you for your understanding.
