['I walked into class yesterday fully unprepared for our final exam.', 'Oh no!  What happened?  Do you think you did ok anyway?', 'I did terrible, I will most likely have to take the course again.']
That's sad to hear :(  That happened to me before and I came out ok in the end, I'm sure you will too :)
I walked into class yesterday fully unprepared for our final exam. I knew for sure I would fail and not pass the class
