<p>How much harder is the 31 series compared to the 3 series? Does the 31 series cover everything that the 3 series cover?</p>
<p>.................please search in the forums as there are literally hundreds of other posts regarding this matter and other similar questions like should I take chem 14 series or chem 20 series? </p>
<p>Math 3 series - life science people
Math 31 series - engineering, physical sciences people</p>
<p>I'd recommend that you take the 3 series if you want a good chance of getting an A. There will be a lot of engineers/pre-med/physics majors in the 31 series.</p>
