I think I've got this, but please can anyone just confirm.
The syllabus overlap means that 2017-18 pieces are actually valid until 31 May 2019? So since the spring exam period (period A) isn't as late as May, more like until mid Apr, valid until the end of that period?
Is there any restriction on taking different grades within the same syllabus? Eg if I took grade 4 this June/ July, grade 5 in winter or some time in 2018 and grade 6 in spring 2019, all from 1027-18 syllabus, is that allowed?
