<p>Hello, I will be a freshman in college this year, and I was wondering what the benefits of taking harder college classes is, esp. if they fulfill the same requirement?</p>
<p>For example, Physics 20 series, Physics 40 series, vs Physics 60 series?</p>
<p>Do grad schools or companies care about them at all? </p>
<p>Or should I just concentrate on GPA instead?</p>
<p>Thanks!</p>
