DO NOT TAKE S117 UNLESS YOU LOVE PHYSICS AND ARE WILLING TO STUDY FOR HOURS A DAY. I was a 4.3 student in high school and this lass single handedly jeopardized my chances at admission to med school. Be Careful

Don't take S117 unless you have taken AP Chem, AP Calc, physics AND statistics in high school. He assumes you have a TON of background knowledge that most people do not, everyone is so afraid of him that no one wants to ask questions, and the expectations for the tests are never explained. By far the most disorganized and hardest class I've taken.

Horrible. If you can't follow spoken calculus and phyisics don't take a class with him. He writes FAR too little on the board. Also be prepared to be compared to his middle-school-aged son, who "understands this stuff," with "stuff" being quantum mechanics.

He trys and fails over and over. Had to find a much better teacher on youtube.

I liked Prof. Iyengar at first because he was enthusiastic about chemistry and kind of made class engaging. It wasn't until I went to office hour that I realized he was disrespectful and unprofessional. He is rude to students trying to understand concepts, and puts blame on the students for the mistakes he makes. Would NOT recommend!

The most disrespectful person you will ever meet. He doesnt teach and its rude to students when they have a question. The way he talks to his students should NEVER be allowed. Ridiculous that he gets away with it.

Srini's class's very hard. That's not the problem. He's very unprofessional. Not sure why but this department hires faculty who are have absolutely no social skills. Srini must have been hired using the buddy system cause you need social skills to be a teacher. Anyone can be a researcher. If you are a Chem major switch fast. this dept is awful.

Terrible professor. Took C117 online and he is not enthusiastic at all. Its almost like the chemistry department wants the students to fail so they gave us him. He does not explain anything at all and is simply the most boring person ever. Do not take this professor unless it is the only professor left.

Prof. Iyengar teaches only the second half of the class. I did well in the first half, but struggled when he took over. He simply reads the slides, which are very unclear and have little information. Lectures teach you very little, so reading the textbook is necessary. Homework and exam problems are never taught in lecture. Very frustrating!

AVOID HIM. Grades were not available to us until after the final was graded. We were all left in the dark. When I had emailed him about this he said that a real grade couldn't be computed bc the final was a lot of points. :/ Also we never had live class, only pre-recorded. Not helpful when you have small clarifying questions.

Terrible teacher. The IU chem department simply doesnt care about their students because they gave this professor for this hard class. I got a B on all my exams (class average was around a 65 %), and got an A on the final, but I still ended up with a B in the class. Terrible grader and the worst professor I have EVER had!

Dude's slide were hieroglyphics. Heavy accent makes it difficult to hear what he's saying. Most people stopped going to lecture and learned the topics off youtube. Professor for first semester was better, although boring. Not finished with this class yet but this class blows and so do the professors. The group me, youtube, and chegg will save you.

The professor outright told us that we would learn through the homework so you basically have to teach yourself and there's also three lecture quizzes that you have to complete that is posted after each lecture. The only thing that really saved me in the class was the groupme.

This course and professor was the worst. Couldn't understand him during lecture, not only because of a heavy accent, but he would speak really fast all of the sudden, and not repeat information. It was hard to understand concepts, so I fully stopped going to lecture. Be prepared to learn everything on your own. If anything, learn during discussion.

Two words: good luck. Slides are nothing like the homework or exams, so be prepared to read the textbook. I ended up with an A only because I focused on youtube videos and the textbook rather than going to lecture. Lecture was just Prof Iyengar reading off slides and not worth it at all. Go to office hours, this class requires a lot of effort.

Professor Iyengar is a nice guy, but there are so many things with his teaching style and this class in general. I have tried multiple times meeting with him in person, but he has avoided setting a time. I don't know whether this is lazy or because he doesn't have enough time since he is teaching 600 kids, but either way it is inexcusable.

Going from a good chemistry professor to this was a terrible experience. Expect to have to teach yourself the topics, because the lectures are only going to cover the surface level of the many, many homework questions you'll have to do. I bowed out about 2/3s of the course and suddenly I became a lot less stressed and depressed.

He is kinda rude during class to people who ask questions. He is passionate about what he teaches but he sometimes gets caught in tangents and doesnt talk about what is needed. He doesn't practice problems on his slides which is very unhelpful (he will sometimes write them on a chalkboard but his handwriting isnt good). The slides are hard to read

This professor is absolutely terrible and I wouldn't recommend him to anyone. Doesn't round grades up and seldom answers emails. Although attendance is mandatory and counts towards your grade, there is no point in going to lectures since he only covers the surface of every topic. No problem examples on the slides and no practice exam for the final.

He nor his Ai have responded to emails sent months ago, the lectures had nothing to do with the homework, the textbook didn't help with a single thing, the exams had 7 typos minimum, he never communicated anything, he was hard to understand, and talked insanely fast. I took the L on attendance points because lecture became a huge waste of my time.

There weren't any practice problems done in class and if you wanted to learn, you had to spend hours watching youtube videos to understand concepts. Lectures were pointless and all learning was done on my own time with outside resources

lil bro was a trashcan

Im sorry but he is really incapable of being a teacher. He is not open to questions realistically as he provides rude responses his curriculum is very unresponsive and unengaging and overall is not well fit to be teaching any subjects. His course schedule is sloppy and he treats his lectures as busy work for himself

He only covers the general idea of the material, and there are no examples provided to help you better understand how the general concepts actually work. The homework is also consistently very difficult. If you want to achieve a good grade in this class, be prepared to spend many hours outside of class basically teaching yourself the concepts.

The powerpoints are absolutely horrible. He only puts the general idea of a topic in the slides and doesn't elaborate. The examples he provides are child's play compared to the homework he assigns. You'll encounter problems that he didn't provide an example for or didn't talk about. Be prepared to read the textbook often and teach yourself.

Not good, lectures do nothing for learning I have taught myself everything so far from the textbook. The exam was rather difficult and there isn't a curve even though the average was a 64% on the last exam. He is rather hard to understand and going to lectures is pointless.

Not to be racist but bro's accent is hard to understand. Doesn't work out lecture problems step by step but just reads it out. Question? Come to my office hrs/don't worry about it. Bro, some ppl don't got time for office hrs It's almost like he expects you to know half the lesson b4 coming to the lecture. Better off learning by urself.

There's so much I can say that has already been said. All I'm going to say is all the reviews are correct, **do not take this class with Prof Srini.**

Bad professor. Skims over material, does not fully teach concepts and gets upset when people ask questions. Super unapproachable and talks so fast and has a thick accent so it is impossible to understand when he is "teaching". DONT TAKE HIM!

Please listen to us. You will never meet his expectations. He brags about exam averages being 64% (NO RETAKES); takes pride in student failure. 30%+ credit removed from homework question credit for getting a homework question wrong ONE TIME. No safe space to make mistakes. If you ask a question, he will respond with an interrogation.

Don't understand why the chemdept won't help students. Any review here blaming the student for not trying hard enough is Prof. I's writing. He had major typos on 2nd exam cost each of us 15 pts; he won't do anything about it. Other questions made no sense; AI's cannot help. Dept Chair won't help. Students negatively impacted by his ineptitude.

Not a good prof. Reads off the slides and doesn't explain. Homework was extremely difficult and lined up with nothing during class, even AIs didn't know what to do. If you have a choice take this class in the fall with a different prof.

Sincerely, don't do it. I like not to judge a teachers right off the bat, but this course is a horrible experience. All he does is point at work problems than work them through in front of you and expects you to grasp what's going on. The homework is nothing compared to his story-like lectures. For your success and mental wellbeing, zon't zo it.

He flies through material and does not answer any questions. He just points at the slide and does not work through any of the problems. Tests were ridiculously hard for no reason. Do not take this class with him.

He was not a very good at covering the material thoroughly. He would go through practice problems, but he would not go step by step. He would just show the whole problem worked out and expect you to know how to do it. Homework problems were very time consuming, and you have to go to office hours several times a week for help on the problems.

Not a very good professor. He brags about exam averages being 60%, and how his class average is a C-. If you ask a question in class, get ready to be put down and feel like an inconvenience. In exam 2, he had so many typos we got 15 points back. Also had really hard lecture quizzes that were not easy to understand because of typos. -20/10.

Not a good professor. He tends to say "everyone understand? yes? okay we move on." when probably most of the class has no idea what he had just said. Exams are nothing like practice exams... every time I went into the exam I felt extremely prepared, then read the questions and have never seen anything like it before.

for any positive reviews, you should know he's currently being investigated for discrimination against students with disabilities. tells disabled students they must choose between accommodations for exams and other classes bc he won't move exam time for a test he doesn't proctor. the experience was traumatizing. please don't take his class.

This professor was my only option for C117. If you can take this course in a different semester to get a different lecturer, DO IT! He does not do a good job at explaining introductory topics to students and his in-lecture examples are difficult to connect to the concept at hand. I have heard him verbally berate students in office hours.

hardest class ive ever taken

he was horrible. worst teacher/ professor i've ever had. answered questions with the mindset that the student should already know. so many people were struggling that the highest grade after the first exam i heard was in the high 60s (i asked about 15 people). seriously run.

RUN, JUST RUN

Poorly explained complex topics either in analogies or just purely writing formulas. Communicating was frustrating and he insulted my intelligence and work ethic when I asked for help. He complained I didn't come to office hours but would be half-present or kick me out to meet someone else. He forgot to schedule my testing accommodations .

I've never heard a professor brag about a 60% average on an exam, but here we are. 90% of the stuff on the exam and HW isn't discussed in class, be prepared to do a lot of outside work, you will want go to TA office hours if you want any chance of passing. The only good thing I can say about him is that he's passionate about what he's teaching.
