If I want to do the detailed Analyst Pathway but have no previous experience of Python, should I do the Management Pathway first ?

There is a pre-course module where you have an opportunity to do an eLearning course as an introduction to Python for spreadsheet users. This will set you up to be able to proceed with the rest of the Analyst course. No need to do the Management Pathway first, if the Analyst Pathway is the one you want to do.
