<p>Ok so I took physics C elect and magnetism because I thought oh hey I do well in Physics in school , I guess I can do well in the AP too. Turns out im an idiot , Physics in our school is mostly memorizing some rules and doing the same style of questions on the exam .</p>

<p>I didnt understand the material but I memorized the rules, Now Im taking AP Calc which Im doing pretty good in the practice exams and AP physics where I tried solving the first question and realized I have no idea what im doing.</p>

<p>So my question is, Im in a nothing to lose situation now, and I will have 5 days to study for the exam after the math AP what do you suggest I do? The thing which was bothering me in the practice exam was the integrations . I didnt understand how the integral of for example E can you get you V . Never took those stuff in school.</p>

<p>So should I just try solving the exams and memorizing the answers until the rules and stuff get stuck in my head? or should I try reading the barrons book which is extremely difficult and is crap at explaining?</p>

<p>I know Im giong to do bad but if you were me and you were in this nothing to lose situation what would you do? or advice me to do?</p>

<p>bump, any advice to a struggling AP physics student?</p>

<p>“I didnt understand how the integral of for example E can you get you V”</p>

<p>That’s how it’s defined in a conservative field.</p>

<p>Electric fields can be non-conservative if there’s magnetic flux changes within the loop though. But as long as d(flux)/dt == 0, you can rely on the idea of ‘potential’ as a state function.</p>
