Get a check-off Go through the grading checklist in lab with your TA/tutor in person Lock in your score with your TA/tutor Your tutor only Do the write-up Submit the lab assignment by the deadline Both the lab file(s) and the write-up file Submission into the locker is what really counts No difference in grading between in-person check-off and normal grading with file submission Only the submitted files will be considered “official,” regardless of what you showed in classCMPE12 –
