Took a class on computer systems, was supposed to be taught instruction sets, interrupts, pointers, basic gate level digital logic, etc. Professor spent the whole semester going line by line in the Visual Studio disassembler for some arbitrary C code, explaining in painfully dull detail, what each assembly line did. They did this for every class session, including the first, with no introduction to assembly. I lost count of how many times I fell asleep in class.
