For Ultra courses, grades are centered in the Gradebook, which can be accessed via the respective icon in the upper right of your course’s main page. You can then choose to view the gradebook by graded items, student grades, or a gridded view of both.

"Content", "Calendar", "Discussions", "Gradebook", and "Messages" are options on the rectangular horizontal menu, with "Gradebook" being highlighted and underlined for emphasis.
