If you want to use one of the computers in the computing labs of the School of Mathematics and Statistics, both Red Centre G012 and Red Centre M020 are open from 8am to 9pm on Monday to Friday. Booked classes have priority but choose an unbooked computer lab and you will get access to a wide variety of software, both mathematical and general.
All computers run both Windows and Linux, offering a choice of environments to work in. If you don't want to use the environment that a computer is currently working in then simply restart the computer and select your preferred choice when it restarts.
Whilst using the computer labs please remember that it is a shared space so be respectful of those around you which includes not bringing food or drink into the lab.
