You used the singular "examination" here, instead of the plural "examinations".
I have to remember the date of the examinations.
It is only one exam (examination) not examinations (exams). I did that as a test to see if examination would be accepted or not. Exam is an abbreviation of examination. Just like photo is of photograph
Yes. I made a mistake when i wrote this sentence. Thanks!
Can i say the test's date?
