Is doing bad on my first test the end of the world?

<p>So I took my first MATH 140 test. Was on a roll, until time was up, and I realised that due to three unfinished parts, I could only get a 79 max.</p>

<p>I have three tests left, one of which can be cut in half (the lowest grade, so if my lowest grade on a test was 50/100, it would become 25/50), and a 200 point final. 150 points comes from hw and discussions, which I'm pretty much set for.</p>

<p>Oh, and I failed a precalc quiz (15/51 :( ). </p>

<p>So there's a total possible number of 750 points. </p>

<p>So I ask to anyone who has already taken MATH 140, should I be worrying already? My goal is to get a B in this class at least. </p>

<p>I took Calculus back in HS, not AP, but I got a B in it (I understood limits, and derivatives).</p>
