Hi all. Sorry if this is a naive question but I'm quite new to the Moodle's grades, scales and so on.
I have a situation where I have two categories of courses; category one contains last year's courses (which are all complete) and category two contains courses for the upcoming year.
If I want to change the letter grade boundaries for the grade letters (in Site Admin > Grades > Letters) for the upcoming year and following years, I'm wondering what the implications are for past results; would I be correct in assuming that changing the existing boundaries will affect how past grades are calculated? If so, how does one apply a different grading for courses and categories going forward?
Again, aplologies as I'm sure this is a pretty elementary question! Thanks in advance. Darragh
