Hi Vadym Talking about the exam you are going to take tomorrow: a) If you don't prepare properly, you will fail the exam. b) You have not prepared properly, so you are going to fail the exam. c) If you don't prepare properly, you won't pass the exam. But if I study all night long, I will fail the exam anyway. I will be too tired to take it. .... You can write your own versions. .... I hope the example sentences are helpful to you. Happy studying!

- You have to pass an exam tomorrow but you are not ready for it. Are you going to revise all night? - No, I am going to bed. - a) You will fail the exam b) You are going to fail the exam c) You won't pass the exam. I would opt for (b) Then you're going to fail the exam.

b or c are all acceptable, an exam would be for when someone has many exams and if they do not study, they will fail one but we are not certain which one, so depending on circumstances all are acceptable. so you will fail the exam, you are going to fail the exam or you will not pass the exam would all work, you will not pass is a little more soft way of saying it not as blunt.

You won't be able to pass the exam.
