Too much?

<p>I'm an upcoming Junior at a public high school in New York. I've always been an Honor's Student and have always maintained straight A's in all of my classes. For my first two years of high school I participated in debate, and was very thrilled by it my first two years, and even attended a two-week forum over the summer last year to enhance the activity. I have recently decided to not continue on with it, as it is too much stress with the onslaught of work I undoubtedly will have. I wanted to take on cross country this year, as i love to run, and seeing as i dropped one of my ec's, it may make up for that hole there.
This year I will be taking 2 AP classes, and 3 college courses (two through a community college class hosted by my school and one from a private university, also hosted by my school).
My issue is this:Is taking on a new sport with 5 hard classes too much, especially for my junior year? I am also in the orchestra at my school and do play in the orchestra for the musical in the winter which takes up quite a bit of time, along with being in Tri-M Honor Society.
Is it all too much? Or with a little time management will it be alright?</p>

<p>I would stick with the plan you have now and lower participation in cross country as it becomes too tough to handle.</p>
