In class final for a graduate EM class?

AI Thread Summary
The discussion centers on the educational value of final exams based on the Jackson textbook, highlighting concerns about the difficulty and integrity of the exam process. One participant notes that typical Jackson problems can take at least two hours to solve, leading to frustrations with grading and the potential for mistakes. The professor, inexperienced with the material, caught several students cheating on a specific problem, opting not to grade that question for those involved. The conversation raises questions about the effectiveness of such exams in fostering genuine learning, with some participants sharing experiences of less challenging exams in previous courses. Cheating methods included copying solutions verbatim from posted materials, which participants agree undermines the educational purpose of the exam. The consensus suggests that in a small class, such dishonesty is easily detectable, further questioning the integrity of the exam process.

I question the educational value of such an exam. We've been working out of Jackson this year, and based upon my experience the typical jackson problem (just one) takes at least two hours, even if you know what you're doing and make minimal mistakes (ie dropping signs, forgetting terms in your algebra).

The professor hasn't done it before, but this year he caught several students (maybe 3 out of 7) cheating (on problem 5.26 - the prof has yet to work out the quoted solution). No, I was not one of them. I made a completely boneheaded mistake (calculated the integral of B*B between the two wires, as opposed to over all space). Instead of reporting the problem to the dept. chair he simply didn't grade the problem for those students (they got a score out of 30, the rest of us out of 40).

In any event, I'll quit ranting. To get to my original point, for those who have had to take an in class final for Jackson, was this educational for you at all?

How did they cheat?

In fourth year, I took two 1-semester courses that had Jackson as text and assignment source. The final exams were four hours long, and the exam problems were somewhat less difficult than Jackson problems.

I would rate the value of this type of exam as about the same as most exams.
 
from what I understand, they copied from a posted solution, verbatim.

Personally, I think it's one thing to check a solution to see if you're on the right track. But to copy something is wrong.

And to think they could get away with it, in a class of seven people? If any two people in a class that small do a hard problem with exactly the same work and with the same writing, it should be pretty obvious that the professor is going to catch it.
 
Hey, I am Andreas from Germany. I am currently 35 years old and I want to relearn math and physics. This is not one of these regular questions when it comes to this matter. So... I am very realistic about it. I know that there are severe contraints when it comes to selfstudy compared to a regular school and/or university (structure, peers, teachers, learning groups, tests, access to papers and so on) . I will never get a job in this field and I will never be taken serious by "real"...
Yesterday, 9/5/2025, when I was surfing, I found an article The Schwarzschild solution contains three problems, which can be easily solved - Journal of King Saud University - Science ABUNDANCE ESTIMATION IN AN ARID ENVIRONMENT https://jksus.org/the-schwarzschild-solution-contains-three-problems-which-can-be-easily-solved/ that has the derivation of a line element as a corrected version of the Schwarzschild solution to Einstein’s field equation.
