Internet Explorer* 5.0+ for Windows or Mac (OS 9 or X)

Other browsers may work, but some functions are limited. SnapGrades has not been tested on mobile browsers.

* Note that Internet Explorer for Windows is an unstable browser. It works fine 99% of time, but sometimes it produces mysterious problems that can be fixed only by deleting its cache. These bugs are not specific to SnapGrades, but they are more noticable when you use a web application as intensively as SnapGrades. Firefox and Safari do not have these problems, plus they are faster and have a built-in spell-check.

No plug-ins are required.

A high-speed internet connection is recommended, but some teachers do use dial-up.
