Assume that Alice took an exam last week and she got its result yesterday. So she knows whether she passed the exam or not.
Now here is Bob. He does not know the result of Alice's exam yet. And Bob is explaining Alice's situation to you:
If she did not pass the exam, she has to leave the collage.
I think that this sentence is wrong, because the IF-part sounds a subjunctive mood, so Bob would not believe that Alice passed the exam. But at least Bob can imagine both situations.
How can I correct Bob's statement?
