I reads: Dear student, In light of you (Such grammer at my school????) results unfortunately not (Really now???) allowing you to proceed with your intended post 16 application see either:
Mrs XXXXXX, Mr XXXXXXX or Mr XXXXXXX before you leave.
And now I have got back home and ain't trailing back 40 min walk.
With so many mistakes in this I am surprised that the person responsible for writing this still has a job.
