I am truely glad my only class at Vista was his. He's dedicated, spends inordanant ammounts of time making sure each student succeeds, and clear. OO programming can be difficult for beginners, and pitfalls are unavoidable. Mr Thanan got the full class through the course in style and good humor.

Greatest teacher ever!!!

Thananjeyan, while vastly overqualified for his position at BCC, does take his job seriously. He is the only professor I have found competent enough to take multiple courses from (4 so far) and I do not regret it yet. Highly recommended if you want to learn from someone in the computer science field who actually knows what they're talking about.

My favorite thing about this guy is that he provides vastly more information than is needed to pass an intro course. If you do the bare minimum you may pass with a high B or even an A, but if you engage the material in earnest, you can come away with a solid knowledge of the C language and of OO concepts. Great guy, great class.

Very thorough and easy going teacher. Let some stressed out students take the final two days after the original date.

Tough but fair. He takes a hard subject and makes connections with things that relate to everyday life for his analogies. This isn't a skill learned overnight. He goes above and beyond the call of intro to programming, so if you have a problem with that then you might as well stop taking programming classes now.

I took his Computer Science class at BCC. I took it to gain a broad understanding of computer science while considering it as a major. Thana gives you that and wayyy more. He gives really displays his knowledge on the topic, but can explain things very well. Very good class, whether you don't know anything about computers or know everything

Tough class, and I bet all his classes are. He has a PhD from Cal and he is very sharp. Expects more from you than community college level - teaches a Cal type class. Show up, work hard, good luck. Slack off and you will be sorry. Unlike most CC teachers, he will test you on book AND lecture - so you must attend and stay awake. Not an easy task.

Thana is the man. He's one of the professors who shows that they know their stuff. He went very in depth in every lecture, often leaving the topic a bit to give more detail. Make sure to use the book for his tests, all of my tests with him were straight from the book. If you want to learn about computers, he's the guy to listen to.

Great Professor, Though a hard class if you have any questions at all he will help you.

Great professor period. Hope to take more of his classes.

people who rated this teacher poor must didn't want to do anything. homework is super easy!!!!! 5 pages of notes for quizes and u really only need to attend class if u dont have a computer to do the homework.... it is a boring lecture though.

Thana is awesome. He's very knowledgable and a fair grader. His assignments are somewhat challenging but open-ended. If you demonstrate you understand the topics, he'll pass you. During lecture, he goes very in-depth and is cool with answering questions about adjacent/sub concepts. If you're not truly interested in CS, don't take his classes.

His classes are for those of you who really want to study CS as a major. His explanations are nice all the time with very challenging lab assignments, but joyful if you like coding. Hope you do the best to get the strong fundamental of Java as well as get a good grade.

I was fortunate enough to take CIS36B Java Programming and CIS27 Data Structures and Algorithms with Thana. He is very approachable after class if you have any question(s). For CIS36B students, make sure you study Java OCP questions for the final exam. For CIS27 students watch Coursera's Princeton Algorithms course and turn your labs in on time...

Thana is a bit intimidating at first, but he's really warm once he realizes you put effort into his class. A lot of students didn't take this class seriously and fell behind in an entirely doable class. The subject is fascinating and really fun to work on, it's basically just logic problem solving. Try, and you'll be rewarded in knowledge and an A.

Very smart guy, gives opportunities for extra credit. You are required to read the book ahead of time, the course wont make sense without it

Good teacher, very knowledgeable on the subject. Reading the book is a must as the tests and final are based on it. Lectures can be boring, however in my opinion they aren't too important. Labs are a great way to learn how to program but can be challenging if you are a beginner.

One of the best professors I've ever had. Unlike most college instructors, Dr. Thana provides students with challenging assignments so that they will actually learn something (if they care to). I am grateful for all of his classes.

Looking back at the past 5 years of college, Thana was one of the best instructors I had. He made CS very accessible while also challenging me to progress. I also took him for CIS 36B and CIS 27 and I wish I could have taken him for more class still.

Really intelligent guy. Sets you up for success. Very lenient grader. Just wants to make sure you understand the algorithms and concepts. Is okay with minor mistakes here and there so long as you get the bigger picture. This class is NOT an easy A. It will require a lot of work. But if you attend classes and do the labs, an A is for sure.

Combines a difficult curriculum with superb and insightful instruction. However, the labs are very difficult and time consuming. This class was my life for four months. You will need to forgo many earthly pleasures to pass. But, combines toughness and fairness more perfectly than any science class I have ever taken.

Thana is great! I take as many of his classes as I can even if they are not part of the transfer program because he brings so much to his classes. While other teacher use lots of slides and videos Thana uses the whiteboard! Any question you have will be made clear through his drawings, pointing and scribling which is much more personal than a slide

If you care about his class you will get a lot out of it. His teaching style worked for me personally, it might not for everyone. If programming is not naturally intuitive for you, youre going to have a hard time at first, but I think this is true regardless of the professor, he just forces you to actually learn rather than giving you the answers

This is the perfect example of people hating the professor for not being able to understand the material themselves. Programming is a new concept for most, so people blame him when they're struggling in the class. His lectures are very helpful, he goes over the labs (often giving you the answers as well), and has a funny and personality. Take him

Thana is the best CS professor I've ever had in CC. His best quality is likely what's perceived as his worst and that is that he treats you like a University student in a Community College environment. If you make this class a priority and really show that you're trying, he'll go out of his way to work with you.

I have taken all the classes required for my cis associate before I took this class. So, I took this class at the end with Professor, when I found cis 20 is also required. I feel that I should have taken his class earlier. I finally do have confidence in Computer Programming after taking his class this semester. He is best if you want to learn.

I took 27 and 20 from Thana. He picks good texts from top universities. His lectures are detailed. Best CIS lecturer in Peralta. He assigns homework that is too hard and there really aren't resources available to help the students. I teaches at a university level but we skip lab and don't have discussion, GSI's or tutors. He knows the material.

Dr. Tana is one of the best CS teachers I had. His lectures are overloaded with information and details, and his homework assignments are very challenging. But CS major is a hard subject, So it helps great deal when the teacher knows what he's talking about.

Great teacher, took CIS 6, CIS 27, CIS 36A, CIS36B. He knows his subject, respected teacher. One of the best computer science teacher at Berkeley City College.

Prof. Thana is one of the best teachers in Peralta. If you really want to learn something and challenge yourself, Thana is the one. Thana wants his students to be prepared for the tech industry and explains all algorithms and concepts in detail. He doesn't really care about deadlines as long as you're working hard.

One of the best teachers I have ever had. Challenging but only because the material is difficult. I left this class with a deeper appreciation of software and computers as a whole. Lenient grader, warm and open in class discussion, wants you to succeed.

Delightful teacher. Highly skilled at communicating complex topics. His classes will make you a better programmer.

Thana is good professor, but he expects a lot of effort. The lectures were alright, and he answered all questions in detail, but CIS20 covers a lot of complicated topics in depth, and I ended up teaching myself most of it. The textbook, CS:APP, is informative but extremely dry. Assigned reading: 600pg/16 weeks that nobody does. (I did.)

Professor Thana is not for everyone, his class is heavy. If you want to learn a lot, or are expecting to transfer into a good school in CS then this classes give you a glimpse at the difficulty over there. Many of these bad reviews come from students who were not expecting this type of effort into the class. Be ready to spend 3 hours weekly on hw.

This was by far my toughest class so far. Professor is lecture heavy, and assignments are tough. You will get the grade you WORK for. If you're looking for an easy class this is not it. You will earn your grade by how much effort you put into learning the material on your own time. Try to find a serious classmate to work with to help you through.

If you're a CS major & too scared to take this class b/c of the reviews, you got no business being in CS. These are core concepts for real programmers. Thana is tough, but competitive programs you are trying to get into are 10x more difficult. He's bringing you up to speed w/ the students who started their freshman year at a 4-year. So tighten up!

Thana is probably one of the best CIS professors I've had. Sure, if you want an easy A, choose someone else. However, if you want to learn, take a class with him. Just make sure to be proactive. He's patient and understanding when you ask him for clarification. And if you do the homework, you'll do fine on his exams, but they can be a bit long.

I took Thananjeyan's classes before transferring to UC Berkeley. His classes are excellent preparation for transfer and are at a UC level of academic rigor. If you are serious about majoring in CS, take his classes. If you can't handle the workload and expectations, than you are simply not ready for 4 year university level CS.

Thana's class isn't easy, but if you work hard, you can do it. This is perhaps the only class that I remember even a year after I took it. Studying in groups, discussing material after the lectures, and finding supporting materials for lectures helps a lot. For anyone ready to learn and work for it - I recommend this class.

This class teaches a great deal, but it's not for everyone. Here's a checklist to see if it's the right fit Are you confident about C++ or Java? Have you ever taught yourself by reading heavy textbooks? Can you memorize a lot of information before a test? All three are necessary to do well. Lacking one is okay. Two or more will be a struggle.
