I'm so sorry to hear that you're having trouble accessing things through your Online Student Center.
Try logging in and then holding down 'Shift' and 'F5' at the same time. This will perform a full reboot of the page and will hopefully allow you to just hover your cursor over each selection for the drop-down menus to appear.
If you are still having trouble, please get in touch with the school!

I have the same problem when I am on my Ipad, I can only access the forum. But I can get into the assignments and everything else when I am on a regular computer.
Hope you figured it out!
