Is AUTHOR wrong in the post ? POST : Brief Background, I am in college as an engineering major. (Computer engineering to be specific). This issue takes place in math.

&amp;#x200B;

I am in a class that is pretty hard to understand, and I desperately need to learn the material from the professor because it is hard to learn on my own. During class, there is one student, let's call him Jim, that sits in the front. Jim is convinced that he and the professor are best buds and can complete each other sentences, thus he cuts in every other minute during lecture trying to be the first student to the punch, so to speak. It's extremely annoying and half the time he is wrong. This usually derails the professors train of thought, and makes it difficult to understand the topic because every word could be randomly cut off. 

&amp;#x200B;

It is usually something along the lines of:

&amp;#x200B;

Professor: If you look at the proof this way, you can use...

&amp;#x200B;

Jim: (some blah idk)

&amp;#x200B;

Professor: (Pauses) No, we have to use De Morgans Law for solving this 

&amp;#x200B;

It happens so often, I would say 10-15 times a lecture, and it just annoys me so much. He thinks he is the smartest kid ever and just ruins the lecture. Additionally, when he says stuff that is wrong, the professor has to derail his own lecture to explain why whatever Jim said is wrong, leading to inevitable back-and-forth's between the kid that thinks he knows everything and the FUCKING professor who is TEACHING the class. It makes lectures extremely tangential at times, and counter-productive.

&amp;#x200B;

Furthermore, the professor has done nothing all semester to address his behavior, even though this is legit some dumb middle schooler shit.

&amp;#x200B;

My question is: WIBTA for telling him off in any way. He is legitimately interfering with my ability to learn in the class, while also infuriating me and everyone in my class. It just displays a complete lack of self-control and self-awareness.
