Hope that someone could answer these very basic English grammar questions (feeling a bit embarrassed posting them here.. :P):
A. I left university before I had taken the final exam.
B. I left university before I took the final exams.
A. She sacked him before he had had a chance to explain his behavior.
B. She sacked him before he had a chance to explain his behavior.
Are they all grammatically correct or only A is correct?
Thanks!
