Hi @trberg, I wanted to ask whether it would be alright if we included separate code workbooks for our data pre-processing and our machine learning analysis. Although the instructions seem to encourage the use of a single code workbook for both processes, we believe that our methods will be more clear and better organized if we use two separate workbooks. With that being said, we would prioritize avoiding deductions (and potential disqualification) if a single workbook is preferred. Thanks so much for all of your help. Best, Zach
