Cookies & different users same computer

Couple of issues. You only have 4k for a cookie. Now one variable will not take all that, but if you run multiple courses, etc. you can burn it up. Make your course names short as well as your variable names. Second one is how will you distinquish between one person and another? They will have to log on / provide some kind of id. Make it short. You will need to use different variables with each course - not nice but necessary to distinguish between variables. Then you can use JavaScript to do your work. If you need help, post how you will solve the user id and then I will work on the Javascript.
