Welcome to Android Central! What's the exact brand and model of device? Did you buy it brand new from a store, or used from someone else, or perhaps as a floor model? Some devices might have a demo mode--go to the system settings and look through them to see if there is an option for demo mode. Also, go to Settings>Apps>All, and see if there is an app called "Demo." If there is, tap it and tap Disable, if possible.
If the unit was a floor model, it may be that it had a special demo ROM installed. If that's the case, the only way to get rid of it is to root the device and flash another ROM. You'd have to do a Google search for your exact brand/model of tablet and the term "root" as well as "ROM." If it isn't a common device, you will probably have difficulty finding links for either.
