Does Sims 3 University come with a new town?

There is no new town. Choose any town that you want. Only young adult sims or higher can go to university. After you've created your family or choosen a household from your your saved games, click on your smartphone / computer to apply to university. A moving truck will appear at your house, your sim will grab its luggage and enter the truck. After this your game will load a screen that says traveling to university. Once it loads, you will have to chose to live in a house or a dorm. 

the "University" campus is treated as if it's a new world, however you can only play it as a side addition to any main world you choose.

thank you so much you were a really good help.
