I'm still not sure about this one. Whitaker's questions are usually much tighter than this (although this was, of course, the question where they had to issue an amendment so perhaps the compiler had an off day!), and I too can't find any specific reference to 936 AND 962 in the 2013 edition, or the 'June' bit. I've found the 962 - albeit listed under 'July' - and the 936 can be found in the corresponding place in the 2012 edition, but that still seems a bit un-Whitaker's and isn't exactly fair on people who are trying to solve the Quiz just with the 2013 edition!
