Are the following correct?
You will not have reached London by 10 o'clock.
I will not have eaten lunch by 1 o'clock.
You will have passed your examination next Monday.
All three are grammatically correct. Sentence 3 is logically unlikely because there are few situations where someone knows in advance that another person is going to pass an exam they haven't taken yet.
I am not a teacher.
