εξεταση acceptable?
Yes, it certainly should be and I've added it to the incubator. η εξέταση ήταν δύσκολη Thank you.
:-( The incubator is now ok, Troll got to it in time. Thanks to both of you.
Εξέταση was not accepted just then
What was the entire sentence that you wrote?
Did you, perhaps, get the gender wrong and write το εξέταση or ο εξέταση instead of η εξέταση ?
