While going through Swan's PEU, I encountered this sentence in its example:
My parents expected too much of me when I was at school. They were terribly upset when I failed my exams.
Now this triggers a question in my mind.
Which ones are acceptable?
I passed exams
I passed in exams
I failed exams
I failed in exams
Okay, if 'in' is incorrect, how do we say passing or failing in a particular subject?
I passed/failed in math (exams) OR
I passed/failed math (exams)
What if I remove the parenthesis?
I failed math does not seem a valid sentence.
Note: InE seems to be fine with passing/failing in exams as I hear almost everyone practicing it.
