Show strict dropdowlist in my ASP.NET-MVC5 razor form

I need to show a strongly typed dropdowlist in my ASP.NET-MVC5 @ html.begin razor form. There are three model classes in this form. One is a course that is populated by the user and two more schools and campuses to be displayed in the dropdown. I created a ViewModel to combine all three and pass along with the school and campus the list of data in the object.

Now I need to show this razor shaped dropdown menu, how do I do it ???? I need to select the school and campus ID of the selected name from the dropdown.

controller

  [HttpGet]
    public ActionResult CreateStudentCourse()
    {

        var _studentCourseModel = new StudentCourse_ViewModel
        {
            _schoolList = _studentProfileServices.GetAllSchools(),
            _CampusList = _studentProfileServices.GetAllCampus()
        };

        return PartialView("CreateStudentCourse_Partial", _studentCourseModel);
    }
