ahh! I just checked my advising folder, and it said:
"HASS-D Lottery subject choices not awarded, or HASS-D Lottery not entered. "
?! The lottery isn't on a first come first serve basis is it? I did fill out my form kind of late, but it was before the deadline and I did get a confirmation. I put six choices down, so I don't really see how I couldn't get any of them.
