There are lots of services that have direct URLs – it’s quicker to just go directly to them rather than going to the bucknell.edu and following a series of links. Here are some of the most popular sites:
MyBucknell: my.bucknell.edu
Moodle: moodle.bucknell.edu
Bmail: mail.bucknell.edu
Calendar: calendar.google.com
Drive: drive.google.com
You’ll end up at the same CAS authentication page, but once you enter your username and password, you’ll go directly to whatever service you need.
