"Apologize for my teacher....."

Good afternoon Miss Maria de Lourdes, my name is Luis Vaca and I´m writing to say I´m really sorry for not going to the exam tomorrow. I had a recovery class of Inorganic Chemistry Lab in the moment of the exam, because I couldn´t attend this classlast week, I had a very bad stomach ache and temperature.

I would like to know if I could do my exam in the other shedule, I wouldn´t like to fail in this test.

I´m looking forward to your soon response.

Greetings

Luis Antonio Vaca Salazar
