They have been using it all year with no issues. Unfortunately for some reason as they are currently trying to use it for their create PT, the pdf that is generated does not include all the line numbers in the code. The code is all there but the numbering doesn’t appear until line 100-ish. Different laptops have been used and there is no rhyme or reason as to why this is happening.
@mbakas As Jeff mentioned, the line numbers are very helpful if there. Remember, the course is language agnostic. The are curriculums that use Snap and Scratch programming which are block based languages. Those do not have line numbers. The AP Readers are able to follow and score the tasks.
I believe that the missing line numbers occurs when a line of code is too long. I have had students break a single long line into multiple shorter lines. Or change it to 10 point font (but College Board doesn’t want less than 10 point!). And the missing line numbers seems to be an issue on a page basis… some pages have line numbers and some do not.
