Check the web sites of colleges of interest to see what level they prefer to see. Many of the more selective colleges prefer to see foreign language up to level 4 or AP level.
But also check the graduation requirements of your colleges of interest. Completing a higher level in high school may mean needing fewer or no college courses to complete the college’s foreign language graduation requirement.
