This is a tool I made in my free time to let teachers call on students randomly and mark their responses. For me it's mostly for fun, but maybe it'll be useful for you. You are welcome to it, but I can't guarantee it'll work perfectly or be around forever.
If you do use this product, make sure to not lose your password! I have no way to either retrieve your old password or mail you a link to make a new password!
If you notice things that should be fixed or have questions or comments, you could try e-mailing me, Craig Weidert, at firstname.lastname@example.org, but no promises.Cool. Let me try this thing.
