Gap Year Between Junior and Senior Year of High School?

<p>Hi I'm thinking of spending 1 maybe 2 years to pursue extracurricular activities instead of starting senior year of high school at the appropriate time. I'm about to finish junior year of high school and going to take the SAT in May. Will UC colleges still accept me if I start senior year of high school in 2015-2016 or will it be too late by then?
My Grades in high school have been straight A up to this point and right now I am taking 3 AP and hoping to finish with 4.3 GPA. </p>

<p>Or will colleges only accept you if you go through high school without doing any gap years. Will it be to late and I have to go to community college and then transfer? At the moment I have gone through high schools without skipping years or even missing 2 days of school in fact. </p>
