<p>I've heard spring because most students will be coming from the 20 series and the curve is better. However, is it really better to take it in the winter than in the spring?</p>
<p>Eh, I have heard it go both ways from different people. Check out the course rank sight. I’m sure some people have commented on math 51.</p>
<p>Spring is generally considered to have the easier curve. In all honesty, I don’t think it matters so long as you don’t take it in fall if you’re not hardcore math/engineering.</p>
