Options for the future

<p>I am going to to headed off to college, but I do not know my exact path for a career.
I am tentatively going to dual major in exercise science and biology because the beginning coursework is much the same. My path right now is to go into physical therapy grad school, but I was wondering my options if that path does not pan out. If I some how pull off amazing grades I might consider med school, but I not focused on that now. All advice is welcome. Thanks!</p>
