No textbooks, tough grader, just have to pay attention to his lectures and you will be fine. Exams are pretty easy but you have to work hard for assignments. His methods are different for a reason, he teaches concepts which you will be using in your professional carrier. Take his class if you really want to know the subject.

Tough but fair. Assignments are hard but he is always available (even debugs your code for you) and helpful. Classes are good (lots of in-class examples with everyone getting hands-on networking). Projects are cool! (We built an Internet radio!) Take his class if you really want to learn networks AND do well in your professional career. He's cool.

Professor Mani, is a highly motivating and helpful professor. The Programming assignments are really interesting and make your brain reach the next level to solve it. He is an amazing and really a gem professor at NJIT. Full Paisa Vasool! He is definitely a shining beacon of guidance for the person he is! God of Networking from IBM!

If you like hands on, you will love his approach. Teaches hands on networking concept with projects. Accessible outside of the classroom. Instead of giving solutions, he guides you through the path and that is exactly where most of the learning happens. If you want an easy grade, please don' t take his class. But if you are out to learn, go for it.

This professor can turn boring networking concepts into interesting and interactive discussions. He provided examples and involved everyone. Does not test students on theoretical concepts, instead makes you think and apply those concepts in project as well as exam. If you are prepared to work, there is no way you will get a bad grade.

Are you here to study or to enhance your knowledge base? If yes, the here is your man! He will guide you, scold you, teach you, make you work, help you when you are stuck, care for you(By offering Pizza) and in short be your best professor buddy! But to earn this, you need to work hard and be diligent for the work he gives and be logical always!

If you want to understand networking concepts and the day in life of an internet packet he is the professor to approach. He will make you do assignments which clear the networking concepts and you will practically understand the working of OSI model which cannot be learnt by only reading text.

Most beneficial course out of all core courses. Got to know the insight of how data travels over internet. Done amazing projects during this course eg. Proxy server, multimedia radio. If you want to learn IHLP, this is the class for you to be in. Professor is very helpful and is always available whenever you are in trouble.

If you want to learn, push yourself beyond what you know and what you think you can do, and have a hands on approach to the subject do take his class. Challenging projects but will help you learn a lot. He gives full commitment towards the subject and expects his students to do the same. Always ready to help. Helps even with career related queries.

I thought it would be a bookish software class but this prof has worked all over the world and he brings his real life projects from Asia, Europe etc into the classroom and the projects, we built a NYSE trading app (prof was VERY helpful). This is not an easy grade class, but those willing to put efforts will really enjoy & learn a LOT.

Great Professor, but very difficult. Need to put in work to get a good grade. Lectures are very clear and he does a great job explaining everything. Teaches everything in a practical way and tries to avoid memorization whenever possible

Pros: Prof is really good (knowledgeable, open & caring) & really passionate on teaching. Available to help whenever needed (even debugs your code!) Did cases, projects, all very interesting & I learnt a TON. Cons: Doesn't tolerate inefficiency so weak students feel "bad" but its not personal. Great class & prof. Take him if you really wanna learn!

I can strongly say this is one of the BEST profs in this univ. He's full of hands-on practical and real-world examples, he will push you to think, to learn and to do the projects. (I agree he doesn't tolerate lazy/uninterested ppl, also this is NOT a "easy" class) If you really want to learn it then he's the man for you no questions. Great prof!

Worth learning from him. More practical work and coding. Group coding projects and assignments.

Very good class and prof. Focus on real projects, he gives good feedback. But class is a lot of work - not 'easy' but worth learning from him. He pushes hard and doesn't tolerate lazy/phony/coasting. Project on modeling realtime stock market data. Classes are good, he is good in office hours, but you gotta work. He is good.

As a teacher, one of the best at NJIT. As a grader/taking tests, not so good. You might screw your grades. But you may learn many new things under him. His grading criteria is based on relative grading depending on how difficult tests were and how the class performs overall. So passing the class won't be a trouble for most of them.

Great class, he's really hands on and makes subject interesting. Very good projects, you'll learn a lot. Exams are conceptual, find it hard esp. if your undergrad was not in US, you need to pay attention to everything he says in class. It is definitely a worthwhile experience to learn from him.

Really great teacher. This is core network class & the way he teaches really makes a difference. Projects are hard and take a long time to crack. He helped us a lot coz our group saw him regularly. Other groups wait till last minute he will throw you out. He knows all the students so as long as you put efforts youll do well. Can't coast though.

Simply put, if you want to learn, take him. If you want to just get a grade, you might want to look elsewhere. Professor Mani is without a doubt, one my the best professors I have ever had. He is here for way more than just a paycheck; he is here for you. Study hard, pay attention, and really LISTEN to what he is teaching and you will do just fine.

He is actually a very good teacher, knows his stuff, puts lot of effort into the class. Projects are good. Get ready to work, it's NOT an easy class. If you want to learn AND improve your resume take him. Otherwise take an easier prof.

Lectures: Interactive classes. He makes the boring subject a lot interesting. Exams: He specifically tells students which questions/topics will be in exams. Relatively easy. Projects: Projects are difficult but very helpful. Matters a lot while grading and one question in each exam based on the project. CS students must take this course :)

He is tough but upfront and transparent about it. He's also one of the few profs who actually helps debug your code multiple times. He clearly says take another section if you want easy work. He knows his stuff and teaches thoroughly and makes you work, and you do learn a lot. Some don't like him, their choice. I prefer his direct approach though.

If you are here for fun, then DO NOT take classes under him, but if you want to learn, you want to be someone and take the feel of IVY league studies, you should definitely take the class under him. I got an internship in November only by describing his given projects(my work ex helped too but they also asked what you learned in USA).

If you want to learn, don't hesitate to take this Prof. He is one of the best you will ever get. If u just want to take this course for grades, then he isn't the guy. U learn a lot from him more than u can imagine.

He is a great teacher, has office hours on weekends, even debugged my group code. He clearly tells you not to copy (he has auto tools and caught & gave zero to many students last sem) Some didn't do projects and got bad grades. He is actually helpful if you put efforts. He openly says he's not easy grader but you actaully learn lot if u put efforts

He made a very conceptual class to very practical and interesting class. Explains in depth how modern internet works. Full grading is oriented on project. Project is carefully designed to cover all broad aspects of modern internet. He is very strict, so lame excuses won't work, be ready to really work.

He makes us understand, think and solve problems. The classes are full of discussions.

He is the best for data analytics, he puts a lot into the class, homeworks projects etc All very relevant youll learn a lot It is not EASY class however he is upfront about it so take it ONLY if you wanna learn. He is patient and helpful but not to all (esp not if he thinks youre a coaster.) Follow his rules and you'll like it. He's a good teacher.

Professor Mani challenges his students and pushes them to learn the course material. He does this by assigning projects that combine the different concepts you learn during lectures. I advise that students who plan on taking CS656 seriously to take him, otherwise drop. Be prepared to work with bytes in Java and most importantly to learn.

One of the unique data anlytics class you can ask for; I believe it is the only course where prescriptive analytics is taught with actual industry use cases. Prof. Kumar made this subject very interesting and useful for the students. If you want to know how big companies make decision, this is the course you are looking for.

Prof. Mani pushes students to learn the course material. He does this by assigning projects that combine the different concepts you learn during lectures. which i enjoyed . I advise that students who really wants to get indepth knowledge of networks shou take him, otherwise drop. Be prepared to work with bytes in Java and most importantly to learn.

His class is interactive and helps you to understand the essence of the course. Assignments and projects will be challenging but really helpful. Going back to basics is the most important thing when it comes to interview preps not the advanced concepts and he encourages that a LOT in this course. Be open to prepare ahead and research more.

If you want to learn the topic, there's no one better. The assignments are coding based and interesting. He will make you work for your grade i.e. no freebies, however, the quality of lectures and the methodology of teaching is beyond articulation.

Prof. conducts a discussion based class where everyone participates and learn. Sufficient examples are taught in class. If you are attentive in his lectures then 60% of your preparation is done. Professor is very helpful in case you get stuck somewhere with your problem but make sure you have attempted that problem before reaching out to him.

His class is tough. But he is passionate about the subject and he is around after hours to help. He debugged our code many times. I just landed an internship coz the interviews were about his class! Many students whine coz they can't finish his assignments on time. If you really want to learn, take him but if you just want an easy ride then don't.

Amazing professor, shares stories from his professional life and makes the class interesting and relevant. Lots of real world stuff. Available to help even on wknds. If you want easy ride or everything printed out etc you may not like it - but he's upfront about this. Take him, it is totally worth it if you want to learn and crack your interviews!

I really got my money's worth. His lectures are well organized and build on top of each other. He also scaled back the number of assignments required. The class is more of a discussion where you work together to solve the problem. This won't be an easy A, you will have to apply yourself. I learned a lot. I hope to have him again in my other classes

Very passionate about the subject and cares that students learn the material. Lectures are engaging and informative, labs are helpful and interesting. Don't neglect the project, it's a lot of work and instructions might not be clear at first. Take advantage of office hours and ask questions. I don't like the way it's graded but it is what it is.

Awesome. Really knows his stuff and brings lots of Industry experience. Gave lots of insight and detail into data analytics and other emerging technologies. I learned much more than I expected. It is not an easy class. IDK what the other reviews are complaining about - he tells you everything clearly at the start. I loved the experience.

Hands down the BEST at NJIT. Knows his stuff inside out, gives lots of industry details, projects are challenging and great -- same stuff they asked during my job interviews at BigBank. If you want to learn he is TOTALLY your guy. BEWARE - its a LOT of work, if you want easy or step-by-step he is NOT for you. He is upfront about this.

He is def not easy but you learn a ton. It a lot of work youll be coding most weekdays/ends. He knows his stuff but insanely tough grader. Tests are tough you have to study esp math. Write down every word in class, code everything yourself bc exams have code, study your math real good and you do ok. If you want easy take someone else. TA can help.

He knows his stuff and is totally clear w/ expectations. Projects are hard but he helps if you make honest effort and go to office hours. It is not easy. Either dont take him or if you take him be ready to work. Its not cookie cutter class. I got a ton out of it but that's just me. No point venting here and make it harder for other students!

Professor Mani is not for everyone, but if you are willing to learn and read then take him! He is an incredible lecturer that explains every topic with the best details. His exams aren't that hard if you read what he says and pay attention to class. Group project will teach you a lot about computer networks and how everything works. So worth it!

This professor is great, he has engaging and helpful lectures. The projects are straightforward and he gives clear instructions. As long as you keep up with some readings and pay attention in class, you should do well.

Confused by the other comments because the class is pretty braindead. Exam questions are pretty much the practice ones you get, and the labs take like half an hour each. The only difficult part is the projects, but he overblows it and it takes like not even a few days of work. Not a free grade, but not really hard either.
