When i went on the day at 11 i picked up my A2 ones but was told AS ones weren't released till 2 so just went home under the knowledge any you don't get yourself are sent to you. It's coming up to two weeks since they were released, should i have got them by now?
I'd ring up your college and find out what's going on. If you didn't ask for them to be posted I don't think the college will automatically post them. But yes, 2 weeks is more than enough time.
At my college, if you want them posted to you, you have to make arrangements with them - giving them an addressed, stamped (I assume) envelope for them to be sent in. Some of my friends have had to go in to college to pick up results because they hadn't arranged anything.
