Here's another example of an Army Certificate of Education, 2nd Class; not the most pristine example, to be sure, but it's good enough. This one was issued to a Coldstream Guardsman in 1926 after he'd passed in English, Maths, Map Reading and History. I am unsure whether "Handicraft" was permanently struck off this particular certificate or just in this guardsman's case. In any event, history strikes me as being a far more entertaining subject than handicraft.
The detail in the bottom left of this document notes that this form was part of a print run of 25,000 in February 1923.
