Can you show us how you calculated the 59.85? I ask as rule 7.5.7 (b) says that "The
module mark shall be determined by rounding the overall decimal mark to the nearest whole number (0.50 is rounded up)." You've done that, I assume?
Once you have worked our the programme mark, which is probably 25% x (weighted mean mark for best 100 credits at level 5) + 75% x (weighted mean mark for best 100 credits at level 6) - assuming this is an Honours Degree and you completed at least 100 credits at each of levels 5 and 6 - then
no further rounding is applied. You need to hit a minimum of 60% for an upper second.
BTW, I checked the 2022/23 version of the document you attached (it's
here) and they make the lack of rounding clearer that in your version. Your version says (in the headings of the table in 9.1.4 "Programme Mark Calculated to 2 decimal places") whilst the later version says, "Programme Mark Calculated to 2 decimal places (which will
not be rounded up or down to nearest whole number)".
