I tried nand2tetris and my hardware class was one I did best in in college. Yet I found this class and book to be very much "rest of the Fine owl" and I had to refer back to my college textbooks and even my tests to do the assignments. I gave up about halfway through as you had to complete more or less the main part of the CPU. I felt the lectures and text were lacking to say the least. Maybe in the age of the internet (I graduated a bit over 20 years ago) this is the norm these days but I expected the course and text to be more or less self contained.
