Do I have to include all those Advanced Placement columns in my EOY academic file since I'm not reporting any information?

We need to have a comma between all the fields in the CSV file even if they are blank. This means that,
yes, you need to create all the columns in your file. An easy way to accomplish this is to open the file in
Excel, put a space (click the space bar) in cell BA 1 (column BA, row 1). Then copy that cell down the
column BA for all the rows in your file. When you save as a .csv, Excel will automatically force comma's
in between all the fields. Column BA represents the last Advanced Placement column.
