Just in case you didn't bookmark the Student Information System login page, here's an easy way to get to it for the rest of your time at UVa without hunting through emails, this blog, or the Office of Admission website.
1. Go to virginia.edu and click on "SIS" in the upper right corner.
2. Click on "Fall" almost anywhere on the page.
If you have already deposited, I hope you noticed the link for new students on the front of the SIS page.
Click on that header and you'll be taken to the Office of Orientation's site and a list of things to do next.
