**An impressive 95% of Electricity and Magnetism alumnae and 97% of Mechanics alumnae would recommend the classes**.

The majority of the reviews focus on course enjoyment and difficulty, the underlying concepts and calculus required, and the importance of practice for and thorough knowledge of the exam.

### 1. Students found both AP Physics C courses tricky but enjoyable

“[E/M] was such an interesting, albeit difficult, course! I personally found it more confusing than mechanics since it had a lot of aspects that were difficult to grasp, especially induction and magnetism rip. It **definitely takes work to understand the content**, but I think anyone’s capable if they’re willing to **sit down and take the effort**!” – AP Physics C – E/M Score: 5

“Definitely **takes a lot of time to understand and practice the material well for the exam**. It’s a challenge if you’re looking for one, and it’s a **pretty fun and rewarding class** with content that isn’t comparable to any other normal high school course.” – AP Physics C – E/M Score: 4

“I found E**&M a little easier than Mech**, maybe since I got used to basic physical concepts. However I routinely found that I had absolutely no comprehension of a concept for a good 3-4 days after it was introduced, after which everything made sense.” – AP Physics C – E/M Score: 5

“The material is hard to grasp at first, but once it clicks, it really clicks.” – AP Physics C – E/M Score: 5

“This was a **really really fun and interesting class**! It definitely is **one of the most difficult courses** i’ve taken though – it really does take a lot of focus and work, but it’s **well worth the effort once stuff finally clicks**. Definitely work through past mc and frqs, since the timing was a struggle for the mc and sometimes the frqs can be curveballs.” – AP Physics C – Mechanics Score: 5

“The credit for this course was **super valuable** for me for college. Not too bad if you get the hang of thinking in a physics mindset. AP test MC section is rushed and difficult though.” – AP Physics C – Mechanics Score: 5

### 2. Both AP Physics C classes require a lot of calculus!

“There’s MUCH more calculus in E&M than there is in Mech, so the **math can probably be a pretty large struggle** for some who aren’t used to it; buuuut, the thing is, after you do a lot of problems, they start to become almost **formulaic**, and **you become fluent in the style of math it requires** … [and] you can focus more on the problem-solving and concept application.” – AP Physics C – E/M Score: 5

“Make sure you have a **thorough understanding of calculus** as you will be required to derive formulas on the exam from general laws involving integrals/derivatives.” – AP Physics C – E/M Score: 5

“It’s a **math-based class** revolving around **complex problem-solving**, whereas Physics 1&2 are more concept-based classes revolving around demonstrating understanding of individual principles; that’s why colleges more readily give credit for Physics C than 1&2 for STEM majors, because you get much more training in both the math aspect and the complex problem-solving aspects of STEM.” – AP Physics C – Mechanics Score: 5

“Try to **get really familiar with the formula sheet**. Do a lot of practice FRQs to get used to the style. The calculus involved is fairly basic so don’t worry about that too much.” – AP Physics C – Mechanics Score: 5

“You have to **understand how the calculus relates to the concepts** and how it could be manipulated” – AP Physics C – Mechanics Score: 4

### 3. Both classes are conceptual – and there’s a focus on problem solving

“**The concepts were certainly more abstract** [in E/M] than Mech, because most electromagnetic phenomena aren’t really tangible, and it’s harder to do labs to demonstrate them; however, it’s still doable material. Honestly, I think the problems in E&M were often a little bit easier in terms of complexity than Mech–I’d guess this is because the math in E&M is assumed to be harder than in Mech, so there’s fewer of the complex multi-step types of problems … important E&M concepts that happen to have more complicated mathematical formulas that are often a little more difficult for students to plug-and-chug their way through.” – AP Physics C – E/M Score: 5

“Be ready to **apply several different physics principles simultaneously to complex, multi-step problems**. Many problems look extremely confusing to people at first glance, but if you take a moment to dissect some of the problems and **break them down into several smaller component problems**, they’re really not bad at all–people just seem to struggle with combining different areas of physics for some reason.” – AP Physics C – Mechanics Score: 5

“Note, mechanics is less definition heavy in a sense, **lots of problem solving** on the other hand.” – AP Physics C – Mechanics Score: 5

### 4. Understanding the grading curve was really helpful for students

“In any case, the **curve is really generous** if you look at the score distributions for both parts of Physics C, so don’t worry too much about making little errors in the meticulous computations, **as long as you can show you understand the bigger picture** and how to apply electrical and magnetic equations and concepts.” – AP Physics C – E/M Score: 5

“The curve on this exam makes it a piece of cake if you at least vaguely **understand the concepts**. Seriously, in past years the cutoff for a 5 has been something like a 50% raw score. **The formula sheet is extremely helpful**, know it front and back (but don’t memorize it – it’s provided on the test). Overall the course is **pretty interesting**, would recommend to anyone interested in physics.” – AP Physics C – E/M Score: 5

### 5. If you’re self-studying, having a tutor helps

“I self-studied this class and I would have struggled a ton with the math without having already taken Calc BC.” – AP Physics C – E/M Score: 5

“Our class’s teacher was very very capable. Students who did their work for the class would do well on the exam. **Suggestions for if you don’t have a great teacher**, may want a tutor or such services that could work with you on some more personal level.” – AP Physics C – E/M Score: 5
