When does it stop?

My daughter is now 18 (April 21), currently doing her A-Levels. Leaves school on the 28th May. Hopefully commenting an apprenticeship, only 12 weeks per annum at uni. The rest of the time is on the job training. £15k wage. No agreement through the old CSA or current child maintenance. When do I stop paying? I’ve been told my last payment is May as well as being told my last is July?

Is that her official leaving date as i think normally it is June time? 
This into is about the child benefit which once that stops so does the maintenance:
When your child leaves approved education or training, payments will stop at the end of February, 31 May, 31 August or 30 November (whichever comes first).
