If you plan on living in Maryland for awhile, as you go to school, you should check with the Maryland Motor Vehicle Administration about how to obtain a MD driver's license. Their website lists the information needed in order to exchange your out-of-country or international / foreign license for a MD one - mva.state.us/DriverServ/APPLY/license.htm.

If you are able to exchange your Hungarian license for a US license from Maryland it will be much easier to get insurance so that you can buy, title and register a car to drive during your time here in the USA. With just an international driving permit (IDP) an insurance company might insure you but will typically want you to get a state license within 30 days or so.

Your age might be an issue with some insurance companies or might make your insurance higher since you are under 25. You can start shopping for Maryland auto insurance now.
