<p>You are definitely on track! Remember: junior year is the most important year, so don’t mess up your good stats :)</p>
<p>However, if your major is going to deal with biology, etc, then you should try involving yourself in activities that deal with these majors, as all I’ve seen are sports and helping other people out, mostly (which is good, nevertheless).</p>
<p>So, my advice for you is to look into a lot of biology/bioengineering/etc activities to do, and participate! You can possibly try going out for an internship or even a job, and during the summer you could enroll in an academy at one of these colleges dealing with your intended majors. If you don’t/can’t do that, then there are always community college courses to take that will not only boost your GPA, it will look good to colleges too. 
Also, make sure to make friends with your teachers, as you’ll need them for letters of rec haha. Hope I helped, and best of luck! :)</p>
