First day of college.

I want in in a full class.

There was one spot open, so i moved a course around to make room for it. After the modification to my time table, the class was full.

How do i get in it?

um...probably talk to your college counselor/academic adviser maybe even the professor...

Ask the professor nicely if they will override the limit and let you in. There's a chance more people will drop it and more seats will open up. My school has a waitlist system, but it's flawed because it will only automatically schedule you into a class if there's nothing else scheduled during that time...but you presumably want to drop one of your classes in place of the waitlisted class, so no time conflict exists where it thinks there is one.

Weren't you the guy who was on the verge of flunking out last semester?

im clinging on.
I failed a course or two which is why i need to get in another class.

If i go talk with the prof, wtf do i say?

Ask how you can get into the class, state that it is a requirement for your major/minor (chances are if it is a free elective they won't give a shit), and say that you dropped other classes in order to get into his/her specific class and it filled up before you could get into it.

Again you should probably speak to your academic adviser and figure out how to get into the class, normally they have the authority to override the max students control (at least mine did).

If i go talk with the prof, wtf do i say?

That you really want to take their class because you're thinking about going into *that field* and the class you had signed up for before wasn't for you, or something like that. Aint hard.

If it's a medium-to-large lecture class then you should have no problem convincing the professor. In my experience they're only really strict about the class limit when there is limited seating, lab equipment, or if the professor wants a really small "discussion"-type class.
