March of junior year seems VERY late to be planning an early graduation. You can read a previous reply I wrote to a similar question here: http://www.collegeconfidential.com/dean/000213
It is too late now to apply to most colleges except for non-selective or minimally selective ones. You have also missed many priority financial aid and scholarship deadlines. In addition, most high schools require four years of English to graduate, and many colleges strongly recommend (or even require) four years of English as well. So, if you haven’t planned ahead and doubled up on English classes, you may have difficulty earning a diploma this spring and being admitted to college. (Note, however, that I’ve heard of some students who leave high school at the end of junior year to start college. If they then take an English course in college, they will get their high school diploma when that college course has been completed. Likewise, some colleges that require four years of high school English will accept these students on the condition that they enroll in a freshman English class.)
If you’re bored in high school and eager to get out, at this late date you might be better served by looking into “Dual Enrollment” programs that will allow you to take local college classes instead of high school classes. This should give you a taste of college life next year and perhaps let you try classes related to your intended career, but this will also allow you ample time to approach the college search and application process carefully rather than rushing through it now and finding that your options are very limited.
