Context: Reading and Spelling age score sheet (eg. a student takes a test and it tells them what their 'reading age' is- 14.03 would be 14 years and 3 months).
Problem: Need to calculate progress for each student + average progress for each year group.
Issues: Have tried converting ages to months using this formula (=12*LEFT(C11,FIND(".",C11)-1)+MID(C11,FIND(".",C11)+1,9)) but ran into various issues (treating .10 as .01 for some reason and producing #VALUE error for scores ending in .00 (presumably because MID function won't work if value below 1)
Action: Have gone back to raw data set (attached). Can you help?
