Incredible course, automating testing could have been improved (more coverage of tests and more rigorous tests). However, I don't believe that was the point of the course or important in what was being taught. It has changed the way I view computer science and I have found it truly insightful.

Some issues along the way where certain things were a bit non-obvious with what was expected of the projects or otherwise would have liked to be able to exchange messages with the instructors on some key questions and issues. But the content is great and I am happy with what I learned.

Just as the first part of the course the second course is equally interesting. So much information to learn from this course yet taught in a very student friendly, intuitive and interactive way. Doing the programming exercises makes this course even more exciting. Check it out!

Absolutely amazing. Learnt more about hardware design and compilers in these two courses then back in the university. And additionally made a childhood dream of mine come more then true - building a computing system at my own (heck, i even got a compiler and OS as a bonus!)

Learning about virtual machines, translators, parsing, syntax analysis, building a high level language compiler, building operating system libraries. A challenging course and very rewarding to complete and come away with a deeper understanding of computer architecture.

This was a great course which tied together so many loose ends for me. E.g., I knew that OO languages would add a hidden "this" parameter, that compiling would get rid of symbols, that malloc worked with a heap, but now I REALLY know how all that works.

Great course! Together with part1, it goes through how a computer does what it does, but in a simple way. That is not to say it's not valuable, it was very cool to see how things work behind the scenes and how they did all that! Best course I've done!

Very well structured, you learn a lot, primarily by doing, which is the best learning. The project where you program in Jack is in my opinion unnecessary, and the OS part is just a bag of random stuff, but overall, one of the best courses out there.

You often ask yourself how computers really work, even if you have a computer science education. You usually learn individual aspects of technology. This course teaches everything. You get the full picture. Very demanding, but definitely worth it!

Great course! Cannot imagine how can I build in two weeks the whole compiling software that translates an OO language down to machine code! Although the part II needs more work than part I, it is still manageable and equally inspiring!

This course is a real gem. It is much harder than the first one though. The principal part of this course is about writing a compiler. Now I feel like I can write compilers :) Wow! The authors of this course are amazing people!

Wonderful course. I am new to computer science. This course helped me understand concepts very well. The project-centred approach is admirable. I wish there were more courses like it and of such fine and unmathable quality.

I really enjoyed this beautiful course for 6 weeks. And it was very challengeable, but exciting for me.

I look forward to going Nand 2 Tetris Part 3 near furture.

Great thanks for Noam and Shimon with this great courses!!!

What an effort by the teachers! Such complex concepts simplified for a large and varied target audience. I thoroughly enjoyed doing the exercises for this course. I am eager to take up the part 3 whenever it comes out.

Great course. Definitely recommend taking it if you can-- this course filled many gaps of ignorance that I had. It is much tougher (much bigger time commitment) than the first course so it's good to be aware of that.

Excellent course on understanding the fundamental pillars of how computer software works. Great lectures are clear and concise, so much so you can finish the course without using the textbook. Fun and challenging.

Great course in every way. I can't imagine how much efforts Noam, Shimon and their team have taken. Everyone who's trying to understand computer in a more comprehensive way should take this course.

Thanks for the course!

I came from the first part and really glad I took it.

Though, OS part is pretty difficult. I was forced to look up some hints on the internet for more implementation details.

Shimon and Noam area outstanding professors who know how to transmit non trivial knowledge. The course is well structured though some lecturers may need more than one-week work. Thanks a lot.

Course materials and project assignment are well-organized, demanding but also motivating. I felt so lucky to have taken both of the courses and really enjoyed them! Thanks!

Part 2 is really more challenge than part 1, but it's worthy. What a course ! I have learned a huge of knowledge of CS for 4 months. Thanks Simon and Noam

tough journey but what I learned in this course worth it. excellent design of course and provides basic foundation for understanding high level language.

very fun,really from 0 and 1 ,i build my own computer and implements my own code language.What's more i use my own language develop a game!

It's the most amazing course that i've ever taken. Thanks Noam and Shimon for your work.

I eagerly await the continuation of the course.

It really deepened my understanding of computers and helped me to be a better programmer. It is more challenging than the first part.
