[flytothesky]

Hello~ Whould you help me how to say this naturally?

A: How was the exam? Did you pass it?

B: No, because lack of 2 marks, I couldn't make it.
Or, No, becasue small of 2 marks, I couldn't make it.
( need to have 60 marks to pass but 'B' got 58 marks, so there is 2marks gab)

A: Oh, What a shame!(or Shame on you! or What a unfortun!).
I know how hard you tried. Don't be turn off, you will pass next semester.
