Attachment

I got an email from a TA today with several reading materials attached to it including a zero KB PDF file. Then I got another email from her, explaining that the PDF file had not been attached properly and we had to download it from a web page. Now that I am trying to download it I see that it is a 48MB file. It is a strange feeling to know that your TA expects a 48 MB file to be attached to an email. I am either gonna fail the course no matter how hard I try or will get an A+ without handing a single homework.
