It seems to me, much like with standardized high stakes testing that students throughout the world partake in, the O.W.L. testing occurs prior to the end of the term.  Think about the years that final exams were cancelled... surely those years' 5th year students had already 
taken their O.W.L.s in order to know what they would continue to study. 

At least, that's my theory.
