The comments have already summarized my opinions on Evangelos. Sometimes his explanation can be a little too quick or confusing, but he is happy to answer your questions in class, after class, and during office hour. He reminds us of the deadlines of homework and upcoming tests. The midterms are not super hard, but make sure you review everything for the cumulative final, because the cumulative final is actually cumulative! Go to his lecture, follow along and take good notes, ask questions, and you will learn a lot about differential equations.

Well-run class overall, my only complaint is that he said the final would emphasize content after the last midterm, which it certainly did not. Regardless, none of the exams are too difficult, but they take up a large portion of your grade so be very prepared for them.

He has these notes that go over every lesson, and there are discussions every week as well. Sometimes there is a quiz during discussion, but he tells you ahead of time what it's on and what lessons you should go over. There's also these long written homeworks that take like 3-5 hours, but he tells you and releases it a week ahead of when it's due which is usually Friday 6PM. The only downside of this class is that exams are worth TOO much. Each exam is like 20% of your grade, and the final is 25%, so if you flunk one, you might be cooked. But honestly, the tests aren't that hard if you know the material. Everything you need to know he teaches in the lessons, and usually, the questions on the exam match the same format of questions from the lesson examples or the practice questions he gives out. He also tells you what lessons to study. Do NOT use Cengage questions to study. That stuff is good practice, but those questions are way harder than the ones on the test. The final, he says its mainly on stuff after the previous exam. That's a LIE, don't listen to that, and review everything. On a side note, he's like unironically fun? The first day you meet him, he looks pretty serious, and he talks kind of like XQC. Then, he knows how to make a math joke randomly that's actually funny, I don't know he's mostly serious. Anyways, he's a good teacher who can solidly teach you difficult stuff. He encourages class participation and makes sure to see if anyone has questions. It's just up to you to take in and apply what you learned. Also, this class does take attendance into grading!
