GPA trend in your 4 years in college

<p>How does one's gpa usually fluntuate during the 4 years in college?</p>

<p>Does it typically go up as you get into a higher year? Or does it typically go down because of tougher materials?</p>

<p>Does it also vary between majors? Like math-harder, arts-same, engineering-easier?</p>

<p>Anyone??</p>

<p>EDIT: I'm an economic major, heading into 2nd year, where the materials get extremely mathematical compared to 1st year (general intro economics and basic calculus and algebra). I'm kind of scared and just wanna see how everyone is doing.</p>
