Very talented and brilliant professor! Always willing to help students and is extremely patient. Explains everything clearly and his powerpoints are super helpful and organized. Dr. Tesema really wants you to learn and will do as much as he can to make that happen. No prior chemistry knowledge required, but this class involves lots of math.

Dr. Tesema is an incredibly smart professor. He's extremely helpful one on one. Optional homework recommended because test are based on it. Posts lecture online, but attendance is recommended. Online quizzes. Extra-credit opportunities. People who have low grades and complain never attempt to study themselves. Class isn't an easy A without effort.

Tesema is the most likeable professor I've had at NOVA. His lecture class is split between online and in-class time. He keeps the entire class' power point slides on blackboard from day one, and gives homework in the form of blackboard quizzes and extra credit. That said, it's impossible to keep up with the lectures unless you studied before hand.

ELI course. Suffers from the same problem all ELI courses have: feedback on exams. He will review your exam with you, but you need to make the effort to go see him about this. Helpful in lab.

He's really nice and easy-going, but I took this class online (huge mistake). He doesn't really give feedback on why he grades exams the way he does, and its hard to learn the material just on your own. But the in-class labs are okay, he's pretty helpful in person. Don't know why he has such bad reviews, he's a decent professor.

Dr. T is one of the best teacher i have ever had. very clear, always willing to help students. he is a young and friendly guy. i took chm 111 with another proffesor and i got a c. but i took chm 112 with him, i understood chm and i got an A. one time he even helped me with a related topic thats not in the course. very nice guy!

Very nice teacher, I recommend anyone who plan to take gen Chemistry at NVCC to take him. He makes the hard staff easy and his ppt notes are the best to understand. Study his ppt notes and do BB quiz and then I guarantee that you will pass with an "A" or at least a "B"!!!

Very good!

I am taking hybrid chem111 with him, he is the best, and his blackboard has everything you need for the course. do the chapter practice quiz and you will get A on all exams.

Dr. T is an excellent professor, as long as you're not a slacker and are willing to put in the work. One of the very best I've ever had...I did not take chemistry before.

He is a good teacher, show up to class, do the quiz and lab you will get good grade. I recommend him to anyone who wants to take chemistry.

You don't even need the text book, everything you need for the course is on blackboard. if you are there every lecture and lab you will succeed and try in the class ask for help he is amazing!love him.

I took a hybrid class so my experience might be different. His exams are very similar to the practice exams you can take online. If you know what you are doing for the practice tests then you should do pretty well. You don't really need a textbook.

I just finished the first summer semester with him and he is a great professor. The course material is difficult so attendance is pretty key, especially in summer session. Go to lecture, go to office hours, and especially focus on the powerpoints (test stuff on it). If someone got a bad grade it's because they skipped class, a lot did.

Great professor. He teachers from powerpoint. However, he elaborates and clarifies as he goes along. Most importantly, he's organized! Exams aren't too easy. As long as you do the practice quiz and blackboard quiz beforehand-study your mistakes- you'll be fine. Labs are fun and fairly straight forward. Don't really need the book. Info comes from PP

Prof T is an amazing teacher! I took 111 and 112 with him. The material is difficult but he makes you understand every bit of it. I had no background in Chemistry but I worked really hard and got the most cherished A ever! His exams are challenging but fair, he gives lots of extra credit quize and practice quize on blackboard.

Dr T is not only an easy going person, but a very good professor. His exams were mostly based on the practice quiz on Blackboard , a lot of questions were taken from the practice quiz. If you want to both learn chemistry and have a good grade, you know where to look for.

He is really nice prof. He knows Chemistry very well, specially if u like maths take with him. I really interested his approach!!!

You will have to study on your own, but he does have office hours that you can go to and he will definitely help! If you really want to learn Chem and can easily understand it I would recommend him. I am really bad at it and could Never get a high score on the exams. but he gives a lot of extra credit which saved my grade! DO THE EXTRA CRED!

I took a six week summer class with him, and his class definitely passable. If you are disciplined enough to use all of the resources that he provides online to practice--which is a LOT of work (50 exam questions for every couple chapters)--you are guaranteed to get an A for every exam. You can get an extra 10% from extra credit.

Lectures are quite long, however, this is chemistry thus it's expected. He moves fast with the lectures but is highly detailed in his teachings. This class will be difficult if you don't study and practice, just as it is with any other class. With Tesema's resources and teachings, you have more than enough to do well. Highly recommended.

This isn't much of a review on Prof Tesema, as I took the class online, and the lectures aren't by him. But, nonetheless, his notes for the lectures are actually where I learned the most. The material is challenging, but if you are able to keep up with the notes and understand the practice problems, I don't think you even need the lectures.

He is very nice and is understanding of student's needs. He covers everything we need to know for the course and his tests are fair. His lectures can get a bit dull sometimes, to me at least. He would take quite a bit of time on some relatively easy and straightforward examples or concepts.

He is a fair grader. Lectures are not hard. 5 tests with 400 points which is quite complicated. Tests are similar to his practice tests. Salping is not require. He only offer about 5 extra credit. He might not help for the lab so you need to read all before come to the lab.

This professor is a nice person. He understands everyone situation, he cares much about his students performance . If you have problems with chemistry, Dr. Tesema is your last stop. Do not think twice, take him. Excellent and clear explanation backed up with examples . I like him as person as well as my instructor. Keep it up!!!!!. Godless you!

Great Professor. He offers a very fair grading scale with lots of extra credits!. Pre-lab quizzes, chapter quizzes, and extra credit quizzes are all to be done at home and are 50% of the total grade. Five exams cover the other 50% while the lowest one is dropped. If you study and pay attention during lecture, you'll get an A.

Professor Tesema is a very good teacher. The class isn't too easy but he makes the process of learning the material very smooth. decent amount of homework and A lot of extra credit.

Easy exams if you study his notes and problems on blackboard, a lot of extra credit, you can also drop final exam, easy A if you study and do extra credit

He's the best chem professor that I've ever had. He's so nice and easy going. Lectures are good, the tests are fair and mostly from practice questions. 4 exams and final exam is optional. Labs are really fun and easy. Pre-lab and chapter quizes are online and open book. A lots of extra credit. Not an easy peasy A tho, u gotta study and u'll be fine

Overall he's very willing to help you as long as he see's you're putting effort into learning the material. I'd sit with him for hours before a test reviewing what I don't know and he didn't show a single sign of frustration. Skipped the final, a few quizzes and labs and passed with an A. It's a chem class so you NEED to study, DO YOUR PART!!

Professor Tesema is one of the best chem teachers I've had. Lectures are long (3 hours) but they aren't unbearable and normally he lets the class out an hour early. 40 points extra credit. Labs were very short (1 hour-1.5 hours max) and fun. 5 exams total, last one dropped (which means an optional final). Very approachable and willing to help.

His test is heavily based on the practice problems. If you dont practice, youll struggle on the tests. His lectures are soooo long, but he does leave time for breaks. The extra credits are worth about 50 points total. Hes pretty quick with answering emails. You have to turn in your work on time, hes not very lenient.

Professor Yohannes is so cool professor. Chm 111 is not easy class,but he makes smooth and easy because he is an organized professor. There are 40 extra credits quizzes from all 8 chapters. His exams are fair and exactly similar with practice problems that are posted with answers on blackboard. Not easy A,but put some effort. You will be very fine.

Thank you so much, Yohannes, for your organized way of teaching. I took chm111 with him. He was an amazing chemistry teacher. so, organized and his exams are very similar with practice problem questions, but you need to ready, Dude. it is college chemistry. Take him.

He is a very nice professor so far at Annadale Campus. His exam was easy if you do the practice quiz and go over each section in one chapter. I would recommend you guys sign up for his class both lecture and lab classes. At Nova, sometimes one course has two different professors which are always happened at Annadale Campus. So far he's very prof.

I took his class 6 years ago, got a D grade, and kept retaking CHM 111 with 2 other professors (each got D's, yeah I didn't try very hard). However I took his class again last fall because I knew he was a down to earth teacher. If you pay a lot of attention to his lectures, he gives hints on tests. His tone may be a little off, but he does care

I haven't had many teachers who genuinely want their students to succeed, however this professor is the hidden gem that I feel many students overlook. He spends SO much time reiterating each concept during the lectures to make sure you digest the information. If you ask questions after class, he makes sure to clarify any confusion you still have.

the best chem prof at NOVA . his lectures are phenomenal and even though they're long I was never bored. he breaks everything down and won't move on until everyone is on board. 5 tests (drops lowest), so so much extra credit and lots of lab reports to write but they're easy once you get used to them. PLS do yourself a favor and take him!!!

If you do the work you will end with an A. He is the best chemistry professor and makes chemistry easy and fun. His exams are very similar to the practice exams and provides extra credit quizzes that will pump up your grade. His labs are easy and he is very approachable, ask and he'll be more than happy to help. I took him twice and got a B and A.

I loved this class. I had a hard time w/ chem before but he made it easy. He offers a ton of extra credit & does a practice exam that has all the exam ?s but tweaked. I learned a lot. He is a little abrasive but it's not personal. I found him quite funny actually. Only negative is lab time is used as lecture so that is 6 hours of lecture a week.

I had him for chem 111 and 112 and he's great! If you're confused about anything including why you got something wrong on a exam/lab his office hours are super helpful. He has extra credit quizzes and fair exams tbh. Ask him questions for sure, he wants you to pass.

Professor Tesema is one of the best professors at NOVA. General chemistry can be a difficult course but the class is so organized and there are so many practice problems that you can master The material. His lectures are great and he does a lot of practice problems and repeats key phrases in a way that i found very helpful.. take him!

He is the best professor for chemistry. There are lots of examples, and he preparing for exams reviews which helps you to get good grades on the tests, also he is so understandable I really had a bad situation this semester, and he helped me out to pass the class.

In my humble experience, Professor Yohannes Tesema is an absolutely wonderful professor for highly motivated students he supportively encouraged observation and understanding of chemistry while giving ample space for self-directed learning. I could not have imagined a better person to introduce me to such an ineffably fundamental discipline.

Very understanding and strikingly patient. I genuinely consider him to be a good role model as both a disciple of chemistry AND as a human being. I personally felt that he exceeded even the expectations I had simply for basic instruction, to say nothing of his ease of accessibility outside class and his willingness to help us with the material.

Very clearly delineated grading criteria. Straightforward, professional conduct. Manages multiple responsibilities well, within multiple class sections. Attentive to students individually and in aggregate. Easily reached by email and in lecture. Overwhelmingly understanding. Genuinely inspirational and impressively humble. I aspire to his example.

My rate score was due to his novice experience in teaching, where he made mistakes in his practice exams and provided study guides. Upon receiving tutoring, we found that he has incorrect answers as the "right" answer in practice test and incorrect question formats in study guides. Other than that issue, he is a great and passionate individual.

Lectures from powerpoints--notes are thorough & clear. 5 exams; lowest dropped. Exams comprise approx. half of grade. 8-9 labs but he doesn't set lengthy post-lab assignments. Take-home quizzes worth ~15% of grade. Prof Tesema is clever, patient, & kind, probably one of the best teachers at this school. Really like him & the workload was reasonable

Really good professor. PowerPoints on Canvas have all of the material bullet-pointed, and he goes over them in lectures, which helps clear up any confusion. Very kind, patient, and helpful, especially during labs. A lot of the tests focus on using the math from each section, so I'd recommend spending time on that. Hope to take him for CHM 112!

I was struggling with chemistry and tought I will fail, but I got my highest score in chemistry which was 1023 out of 1000, gives extra credit, responds to email, helps you if you miss the quiz. Be ready to study, chemistry is not easy.

One of the best professors I have taken at Nova. He is accessible outside class and really cares about his students. The PowerPoints were very clear and helpful for studying for the Exams. He also gives handouts with the formulas and a summary of each chapter. I would definitely take Professor Tesema again.

Took online but he was so organized and helpful. So many assignments and extra credit to boost your grade. The exams are fair and he gives practice exams similar to the real ones!

Very organized on Canvas with weekly updates on what we needed to be working on, due dates for assignments/tests that week, etc. Responds quickly to emails. Took labs in-person and he's great- funny and not overly serious. He kept us moving along, was clear on what we needed to focus on, and didn't let us stress if we messed up. Highly recommend.

Best professor ever! Superb organization, steller lectures, easy to follow content. Has an accent but its part of his charm! Best professor not just at nova but EVERYWHERE. Dont be dumb, take him

Professor Tesema is fun and caring. The class uses a free open source textbook, so costs are minimal. Lectures are often long, but if you sit and take notes through them, the quizzes and tests will be a breeze. Professor T also provides extensive extra credit opportunities, so there is always a way to boost your grade to whatever you want it to be.

Dr. Yohannes is the best chem professor. He is caring, respectful, he cares about his students success, and his teaching is phenomenal. I took his online class and it was super easy. The exams, homeworks, and labs were easy as well. I definitely recommend him, he made learning chem fun and he is also very understanding.

I took his asynchronous second sem chem class with in person lab and it was great! He's a super chill guy and was always happy to answer any of my questions even if they were repetitive. He offers a ton of extra credit, and I didn't even have to take the final because I got enough extra credit points to boost my grade to an A.

I'm a BIO major and struggle with chemistry but Professor Tesema made it easier to understand. Also, your final grade is based on half exams and half homework/ quizzes which have unlimited attempts.

I enjoyed this class and the Professor was very helpful. There is extra credit for those who need to pull up their grades. The Final Exam is optional. There are practice exams that help prepare for exams. There are lab reports; but they are easy to understand and most can be finished in class. Do not hesitate to take this Professor for CHEM!

Took him for chem 1 and chem 2, as a business major who needed to take two science classes, chem seemed scary but it was a breeze with him, and this class. Tests are easy if you study his practice exams and slides on canvas. The labs are pretty easy as he is not a tough grader at all if you need to take a science class consider this one.

Professor Tesema makes chemistry engaging and manageable. With helpful practice exams, extra credit, and clear lecture notes, I felt prepared to succeed. Unstuck study also boosted my study routine. Definitely recommend this class!

Professor Tesema is a great teacher and approaches Chemistry from an easy to understand perspective. Labs are easy with his support and lab reports are leniently graded. However, because he is so diligent with practicing problems in lecture, we did run out of time for the material in the end. -does not respond quickly (or at all) to emails

Professor Tesema was extremely helpful and always available to answer questions. The work load was manageable and participation was mandatory. He offered extra credit that allowed anyone to pull up their grade if they were willing to put in the effort. I highly recommend!

Participation mandatory for a good grade. Extra credit available to improve grade. Always avaliable to offer help. Very caring and supportive; don't hesitate to ask questions and go for help.

This professor was great! I took him for CHM 111 & 112. The work assignments were clear. Labs were group projects. Extra credit allowed anyone to get their grade pulled up. I would take again

He is very passionate about what he teaches, and he is very knowledgeable. Any time I asked a question, he would give me the perfect response. He has an accent, but it's not as strong as others claim. You should easily get an A if you listen to his lectures and study a bit on your own.

Everyone is making fun/complaining about his accent, he's understandable. If you pay attention, do your work, you will get an A. If you are getting Cs in his class, that is a problem within. Lectures are long, it is a 4-credit class; lab is easy. These complaints are all from bums who have never disciplined themselves to work for their education

Chem is generally a hard subject so if you don't put in effort to learn of course it'd be hard to pass. Although the lectures are long, you can tell the prof is trying his best. His accent is not as bad as others make it out to be. Half of the class is graded on lab reports and quizzes that have multiple attempts. You'll be fine if you try.

He was a awesome professor and often interacted with the students after class. I would say he answered every question that came forward and also gave so much extra credit and free assignments. The labs were really straightforward and easy as well.I personally liked the way he taught with his tests being exactly like the practice.

He was such a great prof and wish I could take him again for 112! Labs are manditory while lectures aren't, and he is honestly a very fair grader with lots of opportunities to earn extra credit. Tests were vey similar to slideshows and practice exams. His accent wasn't that bad, and was super helpful for me and my friends.
