I was thinking perhaps late June if people can do that. I finish on the 20th you see
My last exams, M2 and FP3 (if I do it), are on the 23rd June. I'm then busy from 30th of June probably. The whole of the upper sixth go on a holiday every year as a tradition and it starts then.
I think mid-July was best as some people will still be doing straggler exams like STEP which I think has its last exam on the 27th June
