Help a stressed college student polish their formal email to the university administration. Choose the correct word for each blank.

Dear Dean of Students,

The professor to whom I submitted my final essay claims he never received it.

Furthermore, the student whose laptop crashed during the midterm exam was given an extension, but I was not.

I am writing to clearly explain the reason why I believe this grading policy is unfair.

Sincerely, A Very Tired Freshman

The professor to whom I submitted my final essay claims he never received it.

In formal English, we use whom as the object of a preposition (like "to").

Furthermore, the student whose laptop crashed during the midterm exam was given an extension, but I was not.

We use whose to indicate possession (the laptop belongs to the student).

I am writing to clearly explain the reason why I believe this grading policy is unfair.

We use why after the noun "reason" to introduce a relative clause explaining a cause.
