* Country: Exam systems are different in every country.
* Level of education: Are you asking about primary school exams, secondary school exams (like GCSEs/SATs/high school diplomas), university entrance exams, professional licensing exams, etc.?
* Specific subject: Even within a level of education, exams varied by subject.
To answer your question, you need to be much more specific. For example, you could ask:
* "What was the UK equivalent of the GCSE before 1988?"
* "What was the US college entrance exam before the SAT in 1988?"
* "What was the medical licensing exam in France before 1988?"
Without more context, it's impossible to give a meaningful answer.
