My calculus class uses Pearson MyMathLab for online homework and almost every weekend now they perform system maintenance which leaves me unable to login and do my homework. I work during the day so I have to do my homework in the evenings on weekends and apparently that's the best time for them to shut down access for consumers.
Here's just one example: "Pearson will be performing maintenance on Saturday, June 10, 2017 from 8:00 pm ET to 10:00 am ET on Sunday, June 11, 2017. During this time frame you will not be able to access your course(s).
We appreciate your patience while we complete this maintenance. "
