<p>I've already registered for 118, but I am kind of leaning towards 125. I'm majoring in Economics, but I secretly want to do physics. How hard is 125 compared to 118? I took CP Math and AP Stat in high school, so I can't say I'm that mathematically oriented. I'm using MIT OpenCourseWare this summer to self-study calculus a bit. To at least get an edge for next year. Should I stick with 118 (which means I can't do physics courses, etc but it's easier and only meets two days a week) or switch? I really need to maintain a good GPA too.</p>
<p>If you want to take Physics 151, you honestly don’t need too much calculus. All you really need is to know how to differentiate, integrate, and maybe a few things here and there.</p>
<p>Just a note, if you want at least a minor in Physics, the requirements are not only Math 125 but also 126, 226 and 245 as well as the major requiring 225.</p>
<p>Yes, 118 is probably easier and the calculus you will learn is sufficient for general physics classes. But if physics is what you really want to do, you need to understand that you will have to take more math classes than just 125.</p>
<p>You have 3 weeks to add/drop so what I would do is attend both, take a syllabus, see what you can handle and make a decision from there.</p>
