All of the courses offered on our Courses page, https://lagunita.stanford.edu/courses, are offered free of charge. If you have paid for a class, it is possible it is offered through another Stanford department or group.
If you are taking the XEDUC115N How to Learn Math: For Teachers and Parents course or the XEDUC215N Mathematical Mindsets course through the Stanford Center for Professional Development, your course may take up to twelve hours to show up on your Lagunita dashboard page. If the course has not shown up in that time, please send an email to email@example.com to request assistance.
If you are taking a Continuing Medical Education course, make sure you are logged in to cme.class.stanford.edu (and not just regular lagunita.stanford.edu). Once you have logged in there, you should see your course at cme.class.stanford.edu/dashboard. If you don't see the course, use the Support tab near the top left of the page to request assistance.
If you paid for a course that isn't How to Learn Math, Mathematical Mindsets, or a CME course, it may be that the course is being hosted on a different platform, such as Coursera or NovoEd. Those sites are separate from ours, so you will have to contact their help centers if you are having trouble with one of their courses.
