For journalism, Northwestern, Syracuse, ASU, and U Missouri should all be given serious consideration.
Since you will have all of the typical requirements completed after 3 years of high school, then moving on to college is fine if your letters of recommendation include positive comments about your maturity.
Many who major in journalism double major so as to develop an area of expertise (such as economics or foreign affairs). Proficiency or fluency in another language can also be helpful for one’s career prospects.
Based on your shared information, there doesn’t seem to be any reason to prolong high school as your accomplishments are substantial.
U Missouri welcomes qualified non-resident journalism majors with a $1,500 per year scholarship and the chance for additional scholarships.
