We often hear people telling us that the Leaving Cert was much harder in the past, but what were the exams actually like? Over the last few years we have collected Leaving Cert and Junior/Inter Cert exams, so people can find out. We were sparked into action by a Twitter-based claim by a friend who claimed to have had studied differentiation and complex numbers for Inter Cert mathematics in the 1980s (spoiler: they hadn't). We have collected many of the STEM exam papers from 1925 to present day. Why 1925? Well, that's the first year the Leaving Cert and Inter Cert were examined by the newly-minted Department of Education.
