He is a nice person, but his teaching style has a lot of flaws. First, teaches straight from chalk and no slides, so you can reference nothing after class but the book. Also, he goes TOO fast in this class, erasing things and doing calculus while you try to write other stuff down, does not take time to take questions until after class. Hard tests.

His HW does not match what he does in class. Offers no concrete examples, loves to show off that he can do high level calculus in a 201 course where it is not required. All his examples use variables and NO real numbers, very frustrating. Also comes across as arrogant and uninterested in helping the students. Would not recommend.

He is the hottest professor ever. His homework and test are all based on the notes, so as long as you write down everything he writes on the board, you'll be fine. this course involves a lot of calculations, but this is normal for econ courses. and he gives extra credit to boost your grade. I really enjoy taking this course.

Excellent at making economics interesting by injecting humor into the lecture. He can move a bit fast for some students, so I would recommend you think seriously about how well you understand basic econ concepts before signing up for his course. That said, econ majors should appreciate how clear and simple his lectures are.

He's a really nice guy to look at but that's not the main point. He does talk way fast as a typical Bostonian and use a certain level of calculus (mainly derivatives).

This course is very inspirational and definitely worth taking. His lectures cover tons of information. Textbook also helps a lot for understanding the concepts. His grading is not clear at all... He does curve the letter grade at the end. It's better to take this class with people you know and trust since grades are all come from group case studies

Professor Koskinen has a good personality and is a very easy-going professor to communicate with. However, his classes rely HEAVILY on quizzes with only 5 questions, if you get one wrong that's an automatic B-. Filled with vague questions and lectures that do not get straight to the point.

Extremely harsh grader who will take any opportunity to discredit work. Though you can debate your quiz grades with him, he will try to get you on any technicality he can think of. He's obviously very competent, but often to his students' detriment. Turns a 101 into a weed-out. Do not take his class.

Teaches the material pretty well but goes so fast. He grades so harshly, you only have 6 quizzes which are 6 extremely difficult questions and he grades so harshly everyone fails them. It is manageable but there were points where I felt so discouraged and like there was nothing more I could do even though I studied so much and went to every class.

I took EC101 as a hub class but he was honestly one of the better professors i've experienced. Yes, his quizzes are tough but it really helps in terms of staying up-to-date with course material. His lectures are actually pretty funny and he has a good sense of humor that makes it a lot more interactive. He also gives alot of real world applications

Prof koskinen is a nice guy but an incredibly hard grader. Case Studies account for 90% of your grade and are very difficult and time-consuming. HW is alright, but there are definitely quite a few of the. Participation and attendance is not necessary but, i do recommend going to class to learn the concepts and for his expectations on the case study

So difficult for a 101 class, and the professor is unhelpful. If you search his name on Google, you'll see lots of people regretting taking his class. Don't repeat the same mistake, you'll notice many students dropping out during the semester. If you're planning to curve the grades at the end of the semester, why not just revise your content?

His lecture has NOTHING to do with what's on the graded homework or the discussion worksheet. He DOES NOT use ANY powerpoint.

Test is open notes(any printed/ handwritten notes as long as they're not digital), but are difficult as they build up and there is never enough time.
