Morning, i ran best case headline success rates last week and found my 17/18 cohort has reduced by around 29, and my success rate increased by 9%. A few weeks back i did the latest upgrade to Maytas and this is the first time i have since ran success rates. I am having a great deal of trouble trying to unpick what has changes with this amount of significance! Ive read the changes to 16/17 qar set rules and this has just added to the confusion.
Has anyone experienced this level of change? if so can you point me in some sort of direction?
