First, you often don’t need great grades in sciences to get a job: you need decent grades. But if you have no aptitude for it, or if you are struggling through intro courses that science majors usually breeze through, then ignore this.</p>
<p>Second, if you want to know which jobs would require good writing and public speaking skills, try working for a couple of years. Get an internship over the summer. (I am a good public speaker; I channeled that into a job as a spokeswoman. But that is a very, very tough way to earn a steady income; it is more useful as a way to gain exposure and have a really stand-out section on a resume.)</p>
