King’s Student vs BenchCalc

Need to see your King’s timetable on the go? It’s in the app. Want to hear what’s going on across King’s campuses? It’s in the app. Looking to access King’s student systems easily through your phone? It’s in the app. The King’s Student App is designed to help you navigate student life quickly and easily on the go. It allows you to access key systems like your timetable, your student record, your email and online learning spaces all from a single place, without the need to log in repeatedly through the day. Pages in the app provide information and updates about a wide range of services and let you know about opportunities you can get involved in outside the classroom. You can follow pages that interest you to enable notifications direct to your mobile device, helping you stay up to date. Built with all our students in mind, from new undergraduates to experienced researchers, the King’s Student App is regularly updated with new features and information based on what you – our students – tell us you’d find useful. In the app, you’ll also find: · Your student record at your fingertips, with direct access to common tasks · A newsfeed showing key updates from across King’s · A list of major events happening on campus · Links to things to do, like workshops, drop-ins, and clubs and societies · Student life benefits that you can take advantage of
