I don't recommend.. She lets people walk all over her in class, but unfortunately this is the least of my concerns. Her tests don't cover the material very well; "grade-boosting" group work has significantly lowered grades!; homework is poorly selected and rarely explained; AND, she circumlocutes around questions (and therefore never answers them!)

Not a good professor. Seemed uninterested in the class. She was sometimes even just rude. If someone gave a wrong answer, she would shut them down. Once, she (probably unintentionally) called a poor girl fat in a demonstration in front of the entire class. She curves the tests like crazy though, and if you do your hw, you should be okay.

Wouldn't take again

First off I want to say that she is very smart and she knows what shes talking about very much so. However, this is not reflected at all in her teaching. She fails to communicate very often, does take-home quizzes that are due 3 hours after class, and when asked for help she replies do better on tests. Do NOT pick her for physics if you are busy

Kariyawasam is a genuinely nice professor, who cares about her students success and will help them individually. Her lectures however are hard to follow and do come directly from the textbook, just with less information. To get a good grade you MUST read the textbook before lecture so you understand what she's covering. Also go to SI it's great.

I have no doubt that Professor Kariyawasam is a wonderful person, however her class was a major struggle. Often times, after sitting through a lecture, I would be left more confused than when I started. I just ended up reading the lecture notes myself. SI sessions are an absolute requirement though. She will give extra credit for attending SI.

Professor K is a nice person at heart, but she bases her lectures on expecting you to understand. Very fast, doesn't explain things thoroughly. Gained an easier understanding on content by going to SI, which also gets you extra credit. Strong accent and difficult to read writing on the board.

Lectures were hard to follow, and although she had a microphone, she wouldn't use it. Makes it hard for students in the back to understand. She seems often busy, and hard to reach out for if you need help. Be sure you go to SI sessions, or you will not understand the material at all.

You really had to put in a lot of effort to be successful in this class. She is VERY inconsistent in grading. Makes little time for students. I had to talk to her multiple times about errors in the gradebook as she does not respond to emails. All test/ quiz/ homework problems are directly from the textbook, so tests and quizzes are straightforward.

Physics is a hard class and SI sessions are crucial. She takes her dogs out when you go to her office hours and really cares about her students. True story. She talked about how much she cares about our success. Sometimes her lectures are confusing, but you just have to put in the work outside of class. Decent professor would take again.

Shes a decent professor. She cares about her student's success but sometimes struggles grading things on time. She gives group quizzes and Tests are pretty easy as long as you prepare. SI sessions are a must and gives you extra credit for them also gives extra credit for not missing class. As long as you practice outside of class you youll be good.

Worst professor that I have had at the University of Dayton. The physics department should be ashamed of themselves that they have her doing lectures. It is very obvious that she is just there for her research and could care less about teaching. If you think you can teach yourself and still have free time, think again. This class consumed my time.

Kariyawasam is a nice person, however her lectures are boring and hard to follow. There are group quizzes every week which are not easy. The tests are equally difficult and they are solo. Thankfully, she offers 1% EC on the test for each SI session you go to which is the only reason my grade remained an A-.

She makes the course way harder and almost impossible to learn. I was drowning under the loads of homework(graded), weekly quizzes and tests that she made very hard to study for. Every person I knew in her class had a low grade and had no idea how to do it. She seemed to fail to realize that students had more to work on than her class.

Prof. Kariyawasam genuinely cares about her students and is a sweet person, but she is one of those professors who is too smart to teach a beginner level and doesn't understand why the class is struggling. Reads off slides and grades harshly (taking off many points for small mistakes). Gives LOTs of extra credit and is available when you need help.

It's obvious she's very knowledgeable about physics, however her lectures are just copied from the textbook, and she doesn't explain things very well. Go to the SI sessions, she gives extra credit on tests for every one you go to. Overall, however, I'd just avoid if you can.

She can't teach anything. If you never had a strong basis of physics avoid this class. She'll go over problems on the board without explaining them. However she gives lots of benefits with grades. If she sees a class did poorly on a quiz she'll take off a question. She gives extra credit with SI sessions and attendance. She's caring but can't teach

Easy class, bad professor. You most likely won't learn anything in class because she is too hard to understand and goes too fast. She gets upset easily and honestly shouldn't be a professor. I honestly feel like I did the minimum in this class but still had to teach myself mostly everything. Happy with an A- because I expected worse.

WOULD NOT RECOMMEND. Lectures are heavy, and exams are unreasonable in terms of time and question load. You have to either attend SI sessions or teach yourself to pass this course well. Professor K is absolutely abominable at replying to emails, I reiterate... ABOMINABLE. If you want a response you must approach her in person. Avoid at all cost.

Physics can be tough, but Professor K really cares about student success. Lectures can be confusing, but attending SI sessions and using unstuck study for study prep made all the difference. With effort, the class is manageable.

I had her for Physics 206 and she was horrible. We had Si sessions which made up for it kinda because everytime you go to one you get an extra point on your exam and you get points for attendance. If you haven't taken physics before college do not take her because she moves so fast and does not care about the students who are behind.

Took her for SCI190 Lab. Genuinely so confusing and not helpful. I would ask questions during labs and she would barely help or know how to help. I relied on my TA the whole semester. Whole grade is prelabs and labs. Attendence required or else you have to make up labs on your own. Do NOT take her.
