Re: feeling cold
That's fine, but because it is such an uncommon reason, I wanted to make sure that you were not trying to say something else -- namely, that you were ill with a cold.

Many times, posters are grammatically correct, but end up with a meaning they didn't intend. In this case, if you HAD meant you were ill, your meaning was not coming through. As it turns out, your intended meaning was exactly how it read.
I had a cold, I caught a cold, I was sick with a cold, I was feeling ill, etc -- those are things I would have recommended IF that was what you had meant to say. (But you didn't, so you can file that away if you need to write something another time about being too ill to go to class.)
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
