I think the end to this is me buying a new mouthpiece because I'm currently playing on the stock Buffet mouthpiece, but I'm going to present my situation anyway.
I'm playing on a E-11 and as of late it overblows notes as if the register key was pressed down in the chalumeau register.
One director said it might be that my reed was to hard, so I went down to a 3 and the same problem exists.
The clarinet is my second instrument and I'm not really up on something being mechanically wrong with my instrument, so....
Any help is greatly appreciated, I have All-State this weekend!

It may be the mouthpiece, stock buffet mpc's really suck. I don't think its the reed. When I was in high school I had that problem with VD B45, so I switched to a Selmer C*, and never had the problem again. I would recommend a VD M13 or M15 for an E11, Selmer makes some pretty good ones to, worth a try.

sounds like a pad leak - have a tech check it for leaks

If by "as of late" you mean that it didn't always do this, my guess is that something has changed. You could easily see if it can be improved by a change of mouthpiece by borrowing one.
If a different mouthpiece doesn't help, you could test for leaks: plug the bottom end of the upper joint, close the tone holes, blow into the other end, and listen for escaping air.
I discovered a leak in one of my clarinets like this recently. My problem was fixed with a new spring, in place of one which had lost its strength and was allowing a pad to open under pressure.
Or you could have it diagnosed by a repair tech.

Check the register key pad and those on the throat A and Ab keys, and the top two trill keys. I leak in any of them can cause uncontrolled jumping to the upper register.
Other possibilities: a crack in the barrel or near the top of the upper joint, or a leak around the register vent or the metal insert for the left thumb key.
Any repair shop should be able to diagnose the problem quickly and easily.

My student had the same problem so she used a spare clarinet for that lesson. A visit to the repairman took care of it. It's definitely not the reed or mouthpiece.

I agree that a pad is the most probable, but do't rule the mouthpiece out. like I said earlier that is something that happened to me while in high school, the only thing I changed was the mouthpiece and the problem went away. I had a tech check it over and all of the pads were fine. Definitely get the thing checked out by a repair shop though.

Sounds like a leak. Block the lower end of the upper section, close the keys, and blow into the other end, and listen to the air escaping. With the other hand, squeeze the keys mentioned by others until one makes the air stop escaping. If squeezing does not help, then the leak possibly does not involve a pad.
A reasonably common problem not mentioned by others here is...
Where the top two side keys pass over the linkage between the thumb ring and F# keys, they are weak. If one of these keys is slightly bent down here, by a knock, or even by squeezing during assembly, then when you press the thumb ring, it lifts the connection to the F# key, which in turn slightly lifts one of those two side keys, causing a leak.

Double check the screw (on top of the A Key) which affects your throat G# key - make sure that the screw is not too far in which would cause a leak too.

Also, while the throat G# key is pressed down, slowly and sensitively move the throat A key up and down. It is common to have significant resistance, or a stop-start feel.
This is caused by quite a few different conditions associated with the action of the throat A spring (or occasionally rust or a bend in the pivot). I'll detail if there's any interest.
