Your current scores are available online using the Blackboard system available through Route Y. To see your scores, log in to Route Y, and choose the "Blackboard 6" link in the School section.
Once in the Blackboard system, you should see a "Tools" menu with one of the options being "View Grades". Alternatively you could choose the link titled "Quantum Computation" in the "My Courses" menu. Choosing this link will get you to a cs674 page on which there should be a tool button. Pressing this button should provide you with a choice of links, including a "My Grades" link.
Please let me know if these instructions are not helpful or can be improved or if you have trouble checking your scores.
