I am jumping from spanish 3, which it took last year?, to spanish 5, skipping spanish 4. in order to do it, i have to do homework and power point, and later take a test on summer work. I just a got a mail from my teacher that said that the test will be in august, with 2 make-up day and she asked us to reply by tomorrow. I will not be able to come at any of the available days. How do I write it in a polite way? how should i start the letter (Dear... or whatever, English is only my 3rd language and these details are still hard for me)? any help would be appreciated
