Once beginning lab 2b there is a "pre flight" checklist before completing each assignment for this week. Under my "pitches" tab, I am supposed to have P-000-P009, as well as, P-012. Unfortunately, I only have P-000 and P-012. I am unsure how this could have happened because I have received A's on all past assignments. I am unsure how to continue with the assignment without the necessary information on the pre-flight checklist. Thank you.
