Pre-teen

The pre-teen life stage is only available in The Sims FreePlay. It is nearly the same as the Child stage in other games. They can do all sorts of things from hobbies to school.

Hobbies
The community center (previously the sports center, not to be confused with the stadium) is meant for pre-teens. They are able to learn karate or ballet there along with the woodworking benches for the Adults. There are many levels that you can achieve.

School
Like children, pre-teens attend school. They are able to earn money from school, from about §100 to over §600, and will be also able to recieve pocket money from relatives for good grades. If they work hard, they will achieve an A++ grade. Pre-teen sims can study at a desk at home to improve their grades.

Interacting
Pre-teen sims can become best friends, enemies, etc. like adults, but cannot use romantic interactions with any age sim. They can't interact with ovens or plant seeds.

Growing up
Pre-teens can grow up all you have to do if a bake a birthday cake and then they turn into adults.
