It was hard, but he is clear and fair. A nice guy.

Psets can get pretty nasty but overall was an easy class. He gives all (or most) the notes and solves practice problems in class. Sometimes seems to pull things out of nowhere, and he might not understand students' questions, but nice when asking for help. Easiness of tests doesn't even compare to prof dewald's.

He's from the Ukraine and has an accent, but once you get past that, you see that he's a brilliant prof. The problem and lecture sets prepare you well for his tests. He's also really nice outside of the classroom.

He's soooo sweet. The material was simple but he would do anything to make sure everyone understood. He also scales the exams so everyone gets a better grade. Pace is kinda slow sometimes so it might get a little boring but he's such a good teacher u won't regret taking his class.

He does very well preparing you for tests. He prints out lecture slides and does a lot of problems out in class. He's very knowledgeable about the class material. Practice tests really help you prepare for the tests. Online problem sets really help your grade and understanding. Paper problem sets, too. Homework is moderate for a science class.

he's a very honest professor who prepares you well for his exams, which are fair but a bit hard just because it's chemistry. go to lectures! unless you want to memorize the book.

Overall, an outstanding professor. Really understands the material and wants his students to as well. The practice exams and problem sets will prepare you for the exams, which are difficult but always incredibly fair. The online problem sets are annoying but a good way to boost your grade. Overall, great guy. Go see him outside of class.

Very friendly professor, extremely clear. Prints out copies of Powerpoints for everyone and does many practice problems. Has 3 practice tests with answers for exams that are very similar to actual exams and are very helpful. Loves chemistry and does a lot of exciting demoes that made class much more interesting. Homework was moderate.

The class is a lot of work. You will always be doing something for chemistry. But that being said if you do the work you will do well. Lectures are boring BUT clear. All the info you need is there. You can tell he really loves his subject and he is open to meet with students during office hours.

Good class. Crystal clear lectures-->he gives you the lecture slides so thats wicked nice. But if you don't take notes its easy to space out.

Extremely brilliant professor, able to answer any question you may have. Knows how to teach this introductory course in a logical, coherent, and accessible manner. Practice problems are extremely helpful, and puts everything online, with detailed explanations which help for test studying. Lectures are inherently boring, unfortunately.

Professor Krayatov is a quality teacher. He covers a huge amount of material quickly and clearly. He can be a little distant, and don't expect him to learn your name, but he knows how to teach. Chem 1 & 2 are very hard, with a weekly online problem set and weekly paper problem set and weekly labs, but you will know chemistry by the end of it!

I had Kryatov for Gen Chem 1 & 2. Classes weren't exactly entertaining but he explained the material well. He sometimes does random fun things in class like play with dry ice or set hydrogen balloons on fire.

Seems like a good guy. Lectures are very boring -- really you get just as much out of them by printing them out from the internet. Does a good job for it being such a large class. Chem 1 is a little bit difficult but if you do the reading and look at his powerpoints it is impossible to do poorly.

I was really intimidated by Kryatov towards the beginning of the semester. I eventually realized that he is pretty concerned with students' understanding and he's an overall excellent professor. He designs the course really well, so that if you attend lectures and spend adequate time working on problem sets/studying, it is hard not to succeed.

Seems a little scary, but really very nice and concerned with students

Great guy, very clear and very nice. If you read the book and his lecture slides, you will do well in this class. Tough class to teach given the amount of people in it but he does it the best of anyone I have seen.

Kryatov is a great professor, but I really resent the testing. You really have to memorize every little detail from his lectures, whether it seems important or not. Luckily, it's all online in his lecture slides. But especially since this class is also for non-majors, it still digs at me to have to memorize such unimportant facts.

Kryatov is THE best. His lectures are always absolutely crystal clear, and the amount of review material he gives you to study from is AMAZING. Although his accent may make him seem a bit intimidating at first, by the end of the semester you'll love him. The class isn't easy, but he does a great job explaining material in a fair, concise way.

Dr. Kryatov is unintentionally funny at times. The man really knows his chemistry and he'll definitely make time for you if you need to have a concept clarified. Exams are difficult, but manageable.

As a student who had already taken general chemistry and got a 5 on the AP test, the course was still challenging but manageable. Dr. Kryatov is a very thorough professor and wants people to do well in the class. There are always 2 problem sets every week so be prepared.

Kryatov is a great teacher. Has all the lectures and lecture notes posted online so if you miss a class, you can catch up. Practice exams perfectly reflect the actual exams in the class. If you're in his 8:30 class, make sure you sit in the front, that way you definitely won't fall asleep (chemistry can be a bit dry)

His lecture slides are so easy to follow and he teaches the class so clearly, so it is really helpful to go to lecture because he does problem types that show up on the tests and homework. Hard exams, but he's an awesome professor for the subject.

he teachers right off the powerpoint he puts online and only once in a while will he add anything to them. He is very clear . He has a unique sense of humor. Basically he'll do something funny and then show no emotion. Not a bad class to take.

He can be super funny and has an awesome accent. He is extremely helpful, especially if you take the time to ask questions and go to his office hours. He has way more office hours than most professors; he is dedicated to making sure that you do well. His tests are very specific, though, and focus on small details very often.

Kryatov is pretty awesome. Some people find the class challenging, but he gives you plenty of past tests etc. to study from and he is super helpful during office hours. He has a great personality and is a pretty funny guy. I was not expecting to have such a good professor for an intro course.

His lectures are very clear and straight forward. He's actually pretty funny at times and makes the whole class laugh, but you gotta be paying attention, its subtle. The tests are decently hard, but not impossible. Its an intro class, and he does a pretty good job of it. Organized and thoughtful and straight to the point.

I'm marking Hot because of his thermodynamics lecture. Kryatov is one of the most dedicated professors I have ever had. I'm profoundly impressed by his ability to give clear lectures, immensely fair exams/grading, and dedication to his students. He's great.

Professor Kryatov is THE MAN. He's so funny, and his lectures are short, to the point, and he always finishes class on time. He provides tons of study materials, from practice tests to recitation sets to book problems. His class is definitely not easy, and I would consider it a weed-out class. But it's interesting, and you can do well if you work!

I can't put my finger on it but he did something right. I hated chem in high school and did not do great on the AP but got an A in his class cause I went to all the lectures and paid attention. The exam prep materials he gives are super helpful. A lot of people complain about how hard the class is but it's definitely jut the nature of the subject.

Great professor! cares a lot about his students success in the class. He provides Q&A session from his personal time to help the students. I remember once he had one on a school holiday. very dedicated dude

Prof. Kryatov is pretty dry as far as lecturers go but he covers all of the topics comprehensively and provides all the necessary material you need to get a good grade. As long as you study a week or two before each class and use everything he gives you, you'll do fine. He's also a pretty funny guy on top of all that

Kryatov makes you kry. haha I'm funny. But really, I didn't any chem knowledge going into Tufts and I came out and knew my stuff. His tests are hard but not impossible- he gives three practice tests before each. Usually one is representative of the real deal and the other two are easier. The keucces here is READ THE PPTS OVER AND OVER!

The class can be difficult and it has a lot of work, but he's very reasonable. He's fair with grading and curves each test. He's very accommodating, so if you have a problem or question, definitely go to him - he's a nice guy and will hear you out. That being said, he's a bit of a monotonous lecturer. I taught myself a lot of the content.

Professor Kryatov is a smart teacher who is really engaged in what he's teaching. His dry humor really adds to the lectures which are very long and boring at times, though he does move quickly so it is important to pay attention at all times. His lectures are organized, too. Incredibly helpful one-on-one, even in a class of 300+ students.

Professor Kryatov's a great guy. The material can be challenging, but that definitely is just the nature of the subject. His exams can be tough, but overall they're pretty straightforward, and no questions will be unfair. He's always available also, so if you have any kind of issue, contact him, he'll hear you out. Overall, this is a great class.

Clear lectures, but ramps up the difficulty on the tests, big-time.

Professor Kryatov delivers very clear lectures that contain all the information necessary to doing well on tests. Assuming that you complete the onlinepaper homework and put some effort into lab reports, the only really challenging part of the class is studying hard enough to do well on the 3 tests and final (count for 70% of your grade).

There's not a lot of individual attention because it's a big lecture class, but he's always really willing to help when needed and answers student questions fully. He doesn't speak very loud so sitting near the front would help. Also, read the text before getting to class. It makes it a lot easier to understand the material

He aight

Kryatov is a clear lecturer but tends to overemphasize minute details and mumbles important concepts, so its vital that you sit towards the front. There is a lot of work in the course between the problem sets, laboratory and exams, but it is possible to do very well in the course if you put in sufficient time. Overall he is a clear but hard prof

Professor Kraytov is a very fair grader and test writer. The tests are hard but not impossible. Lectures are very clear and he provides practice tests before the exams which are really helpful.

Kryatov is a very clear lecturer and as long as one puts in enough effort and energy into studying for the exams they will succeed. In lecture, Kryatov tends to rush through since the course covers a bunch of different topics, but he is always ready to help in office hours.

Great professor. If you didn't do well in the class it was because you didn't try hard enough. He's very fair, straightforward, and will always help if you ask.

His lectures are clear, but the tests are pretty hard. Go to his office hours.

He is really responsible and his lecture is quite clear. Pay attention to the problems that he gives in class. If you understand the problems in class then most of the homework won't be a problem.

Professor Kryatov is both caring and fair. His practice problem sets and exams are always helpful. There's a lot of material thrown at you, but he understands chemistry well and genuinely wants to see you succeed. He consistently tries to let students out on time and has great demonstrations/short experiments. Attend the many office hours offered.

The exams are much harder than the lectures and homework. In addition, they contain lots of detail-specific questions. However, your grade is not weighted heavily by the final or any one exam so if you put in effort throughout the year with lab and homework you'll do fine. It's a lot of work though.

He's a great professor- super organized and really clear in his lectures but the tests are brutal. You really have to work hard if you wanna do well.

Prepare to work hard, but also be prepared to learn a lot. This class is hard, but it gives a strong foundation of chemistry. Lots of work: lectures, labs, online and paper assignments. Tests are hard, but there will always be a perfect bell curve with the middle set perfectly on a 75. Would recommend. Accent, but easy to understand. Accessible.

Best professor at Tufts -- teaches with a level of detail and thoroughness seldom seen with other professors. Slides for every lecture, multiple practice exams, and curves every exam to an 80. Admittedly can be dry because he is a no BS guy. Those claiming the class is too hard realize they were wrong after taking the remaining pre med reqs.

I think the curriculum is what's difficult. Since there is so much packed in there he will often say that he "can't digest the material for you" which is very true. I had to spend lots of time outside of class reviewing. When he has open Q&A sessions before exams it shows how brilliant he is, even if he misunderstands your questions sometimes.

Tough and boring material that is presented with great clarity and organization. Only take this class if you are willing to work hard. The resources to study are readily available, but you will need to be willing to put in lots of hours to do well. Also, labs are rough.

Prof Kryatov is a difficult professor who values hard work. intro chemistry is very hard. he is a fair grader, but if you don't put in the time you will not do well in his course. comes off as intimidating but he's a fine guy

Kryatov is one of my favorite professors at Tufts. Yes, he's hard. His class may be a weed out, but you learn so much. Those that are dismissing him on this forum are probably pre-medical students that struggled in the course who probably shouldn't even be doctors.

He's a legend!

Dr. Kryatov is a fantastic professor, but he is not perfect. He is difficult to approach, not due to lack of office hours, because he deals with bad questions badly. He moves quickly and sometimes gives unsatisfying responses. He goes above and beyond for his students; he posts answer keys to tests within 15 minutes of the tests conclusion.

Tough class, but if you're prepared to work you'll do well. Lots of resources: problem sets, recitation problems, he releases 3 past exams before every exam. Lecture can be dry but he knows what he's talking about. Often reads directly from slides but goes more in depth; slides are posted ahead of time so you can take notes before lecture.

Chem1 covers a lot of content, and Kryatov does a good job of getting through all the material in lecture. He also teaches very closely to the textbook, which is nice. However, his explanations in lecture don't go into depth about how/why things work, so I found that I had to read the textbook a lot to fully understand things.

if you put in the work, you will do well

Kryatov is a great teacher. His lectures are usually boring and he does read straight off the slides, but if you go to him during office hours he really wants to help you and 100% knows what he's talking about. The people who complain about him are the people who don't do the work he tells you to do. Read the textbook, pay attention during class.

Clear expectations and plenty of resources for students to succeed. Practice tests and answer keys are posted before every exam including the final. Many think he isn't approachable, but he's perfectly fine in office hours. With that said, lectures were dry (just him reading the slides). The course is a lot of work, but manageable.

Sergiy can come across as intimidating and harsh, but he is actually very helpful . He knows that Chem 1 and 2 are weedout classes and designs the class as such but gives tons of practice tests and resources to prepare for the super hard tests. Because it's so rewarding and satisfying to do well, Kryatov's class made me really like chemistry.

I like Kryatov as a teacher. I took honors chemistry in high school so I already knew most of the material, but he does do a good job at explaining concepts. His lectures are fast-paced so I recommend copying down the lecture notes before the lecture since he posts them in advance. Read the textbook and do the practice problems and you will do fine

Kryatov's teaching style often felt dry and intimidating. However, he is extremely knowledgable and is willing to answer questions. Attending the lectures was key to succeeding in the class, and labs are tedious but doable.

Lectures themselves may be average, but he has amazing lecture slides that make for comprehensive study guides. There's definitely a lot of HW (Mastering, paper psets, prelab assignments, lab reports) but they also really help in learning and help your grade. He's very clear in expectations, gives 3 detailed practice exams, and is understanding.

I love Professor Kryatov and his lecture; especially his notes! Although the course may be hard, however, it is the content, not because of the professor.

Lectures are very informative. Clear expectations. Fair exams. Lots of work but they help prepare you for the exam. The class is very very big but he made sure to be available when students need him.

Kryatov can be intimidating but his class is one of the most organized and you can definitely do well. Clear grading criteria, consistent expectations, and he gives you everything you need succeed. You'll have to put in work (chem isn't easy) but the practice exams and problem sets are super helpful.

Professor Kryatov does a great job explaining really tough chem concepts. He's super accessible outside of class and really made the best of online learning this semester. The grading scale is homework heavy which is awesome if you aren't a fan of exams. Can't wait to take more classes with him!!!

Intro courses at Tufts are weed-outs, so Chem 1 is inherently difficult due to the sheer volume of lab reports, homework, and problem sets that students are expected to complete. Kryatov, however, is extremely respectful towards his students and is extremely good at explaining complicated ideas, you just have to be brave enough to raise your hand.

Kryatov is a good lecturer and the course is pretty well organized. A lot of work but more tedious than conceptually challenging.

I had the best chemistry classes with Professor Kryatov! He might seem a bit intimidating, but he is actually really nice if you reach out to him outside the classroom. He always makes himself available, and he provides really clear lecture notes. If you follow his notes, and do his exam practices, you wouldn't have a problem with his class.

Definitely knows what he is talking about. Extremely knowledgable about the subject that he teaches and individual help is very valuable. Slightly threw me off how he structures lessons so that the actual learning occurs outside of class and practice happens during the lecture period. Go to office hours, put effort into learning the material.

Kryatov is a great professor. He explains chemistry clearly and is available for office hours after lectures on most days. The class can move quickly so you should keep up well.

Professor Kryatov is extremely clear and organized. He provides clear lecture notes and answers keys with every step explained. Go to his office hours, he's always available. Very kind to students. As long as you study everything in lecture, practice problems, and practice exams, you're gonna do fine on the exam.

He gets some hate, but he is genuinely caring and knows his stuff.

he is genuinely a nice and caring professor who will make accommodations for you as long as you effectively communicate your needs. the class format is terrible for chem 1/2, where you are pretty much watching lectures in your own time and the actual scheduled lecture is him doing practice problems. he gave me automatic ext on some of the mc psets!

Prof. Kryatov is obviously brilliant and extremely knowledgeable about chemistry. He has tons of office hours + resources for students. Tip: he has a flipped classroom style so make sure to watch lecture videos and do practice problems before coming to class so you can have a better grasp on the material. Independent study = key! Good luck!

I took his course this past summer. His lectures were clear and consistently followed the layout and content of the textbook, which was quite helpful. The content was complex and squished into 6-weeks, but he taught it well. The coursework was manageable, although I imagine it would be different during the school year. Would take his courses again.

Not the most engaging content in chem 2, but Kryatov was absolutely amazing. I didn't mind the flipped classroom format and found the videos great. The lectures are just problems so you're free to skip if you want to. Same goes for recitations. Kryatov is awesome and takes time to both learn your name and thoughtfully answer your questions.

Great professor! I didn't mind the flipped classroom format. If you have the discipline to review and learn material outside of class you shouldn't have a problem with Kryatov or the class.

The implementation of a flipped classroom model didn't help me, but the structure of the course was good otherwise. He is a fair grader (can even be called generous) but the material could have been taught better so be ready to self study

extremely difficult exams but the curve always saved me. very nice guy and decent lecturer. hated the flipped-classroom format

Kryatov is a really good explainer and his tests are (for the most part) fair, chemistry is just a very hard topic in general. I think some topics are unnecessary to learn in a general chemistry class like biochem. Gives lots of opportunities to excel in the class: curves exams to an 80 and gives extra credit points at the end.

He's a good lecturer, and I feel like his tests are pretty accurate to the study guides he gives, and usually a bit easier. He always lets people start tests early, so get there like 20 minutes before the start time. He's kinda harsh but I find it pretty funny. Overall I liked him.

Don't let bad ratings sway you from taking a class with Sergiy.He explains hard concepts exceptionally well and makes it clear that there will be no extra credit whatsoever at the beginning of the semester. He gives MANY opportunities to boost your grade in a fair way tho!He can seem intimidating but is genuinely kind.Your grade is what you put in.

Professor Kryatov seems intimidating at first, but is a genuinely kind person and helpful professor. Attending class reinforced concepts taught in the online lecture videos. Give yourself enough time to do the Achieve psets as they can be time-consuming, but helped me to learn the concepts. Tests are curved to a class average of 80% (super nice)

Is very intimidating in lecture, but a really good teacher if you feel strong on Chem 01 material! 3 exams and a final but all are curved to an 80% average (a blessing lol). Start early on the achieve and problem sets, they can really help boost your grade.

This is a very very hard class. However, he is very helpful at office hours. Make sure you have the time to put in the work since this can be a very demanding course, especially when there is an exam that Monday. I also want to add that he puts a meme on every one of the exams and it is amazing.

I took chem 52 with him over the summer and while the class is lecture-heavy (and admittedly his lectures can be quite dry), he was always willing to go the extra mile to help me understand concepts. Chem 52 is difficult material, but the exams were fair and similar in difficulty to the practice exams.

Kryatov's CHEM02 class is tough, but worth the effort. The flipped format takes getting used to, so utilize unstuckstudy and the practice problems to stay on top of it. Exams are challenging but curved - just be ready to put in the time.

Sergiy is no bs and knows chemistry. It is hard material so the amount of work honestly is necessary. There was nothing that I felt was busy work. Be ready to devote your life to this class (coming from a bio major so if youre very chem minded it may be more chill.) Also very organized.

I loved Sergiy, but definitely the hardest class I've ever taken. Do not fall behind on lecture videos, as it is a flipped classroom. Everything that is on the exams (which are curved) is taken from lecture problems/notes, so practice a bunch. Score 100s on all the labs & achieve and you can get 60s,70s,80s on your exams and still end with an A-.

There's a lot of ways to boost your grade through the Achieve and labs. All 3 exams and the final are curved to an 80% which is super helpful. If you do all the practice exams, and review all the class problems you will be fine. It is flipped classroom, but it's actually not as bad as people say. Just don't procrastinate.

Quite a difficult class but not as bad as people make it out to be. The pre-lecture videos are long so give yourself time to watch+ do the practice problems. Can be condescending but don't take it personally, prep for exams a week in advance. ChadsPrep+Ochem tutor helpful to supplement material. Final exam is heavy on biochem but still cumulative

Kryatov is knowledgeable but is quite scary and his pre-lecture videos are more confusing and way longer than Ravi's. Flipped class - not worth going in person as attendance isn't taken. Exams are hard but if you do well on achieve + lab you only need to have a 84 average on the exams to get an A. All exams are scaled up to 80 as people do badly.

If you're afraid of this guy because of the scary reviews, believe me, I've been there. And it turned out absolutely fine. The key is very simple: stay on top of things. The second you begin feeling confused about something, go to office hours. Use the Staar tutoring resource. Ask friends for help. Do the work, and you'll do well.

Kryatov may be intimidating but if you stay on top of your prework/achieves and seek help when you need it (not right before the test), you will be fine. He has little patience for stupid questions but once you get over the embarrassment, his responses are pretty funny.

The workload is heavy, especially with the lengthy pre-lecture videos. Religious take notes on them since it's easy to fall behind. Kryatov is generous -- he goes over practice problems in FULL detail and answers questions fairly well. Actual tests are WAY easier than practice exams B and C, so make sure to take those and TIME YOURSELVES!!

He does not deserve the hate

Not as bad as people think

All around easy class. Tests are similar to practice problems. Expectations are very clear, if you put a bit of effort in you'll be fine.

Can do well with very little effort. Lot of people like to complain, but tests usually have heavy curve and if you put effort in you can do well.

Currently in the class, people totally overhyping it. Flipped classroom style makes content easy to understand since you can just ask questions in class if you're confused. Tests are curved and based off of practice problems that are given. Really not that bad of a class so far.

Sergiy is so funny. I have never had a teacher who makes me crack up quite like him. If you have a good foundation of chemistry knowledge, this class will be smooth sailing. Make sure to watch the lecture videos before class because it makes class easier, more enjoyable, and you can actually learn and do the problems he gives in class.

Prof. Kryatov is a very solid professor that teaches well and can be funny. The class is a lot of outside work to watch the videos and is really dense and should honestly be broken up into multiple courses. I thought he was a good professor.

He is tough but rewarding. People may complain about the flipped classroom format, but if you manage your time it is easily doable. Psets are long but really the best way to learn the problems. Kryatov is straightforward and blunt, which people take as cold and condescending but he's just being real.

NOT FLIPPED CLASSROOM ANYMORE! blessing on my end cause it allowed me to feel more prepared by reading lecture content in advance and have him cover it in class "again". He does still post all the lecture material plus recorded videos on files and attendance isn't recorded, but I highly recommend actually going to class to understand.

Class was hard, but he provided all the resources needed to succeed. Chem 2 isn't supposed to be a free A but is very possible if you put in the work

Taken Spring 2025. Flipped classroom w/ very dense pre-lecture videos, not sure if this changed. Made it quite boring but you need to attend lecture to grind out problems and ask questions even though he can be a jerrk about it. I took AP Chem beforehand, (so I'm biased), so it was a lot easier. If you didn't take that tho, make sure to grind hard
