Hello:

You do not need to go to a university for modeling.

I would only go to a university if you want to enter a field or get a job that requires a degree (accounting, science, technology, engineering, math, teaching) etc.

You can attend a performing arts college, where you can start off as a "life model". This is where you will be used for an art class, or you can get the opportunity to take up other forms of modeling. Modeling is great but now models are actors, singers, etc. So use your creativeness to build in the modeling industry. Best of luck!
