my days on paper

I've really got to stop this

Man..

This afternoon after lunch, while I was finishing up a project that needed to be handed in by 5pm, I remembered that I had another test coming up for my Physics subject. So I checked the course outline and found out that the test was on the 18th... I had missed it by five days and I wasn't even aware!

That's 5 marks literally thrown away. I really don't want to just throw away marks like that - 5 marks could almost definitely cut me down a whole grade! What should I do? I thought of going to the lecturer and beg for some kind grace marks or replacement test. I even thought of using my not-so-recent cough as an excuse for missing the test, even though I didn't have an MC. I don't know, maybe I should try both? I really can't just let go 5 marks.
