I'm sorry to bother everyone again.This time i have some puzzles about the document Canvas_Network_Person-Course_Documentation.pdf. If i am not mistaken, can i understand the meaning of the grade_reqs is whether a course contains three assignments, if included, the corresponding value is 1? Similarly, the column of course_reqs can also be so understood? right? But in the CNPC_1401-1509_DI_v1_1_2016-03-01.tab, the values of grade_reqs have both 0 and 1. The same to the course_reqs. Why? Should not this be a definite value?
My second question is that the column of ncontent is not given some description in the Canvas_Network_Person-Course_Documentation.pdf. however the nchapters in the PDF that is not in the table.
Thank you very much for taking the time to read my questions,and I would appreciate it if you could help me with the problem.
