I always hit the first day just so I would have the course overview and syllabus so I would know what days to skip in the future
Thats the genius of it though, they hand out the syllabus on the 2nd day of class as well, because of the add/drop period... and because of the add/drop they really dont cover a lot on the first day. its perfect! perfect I tell you!
*note: This plan is not perfect, and is highly unrecommended for anyone actually attempting to do well in college
