How long do you reckon its gonna take to go through all the examples and EOC in the 6 volumes?
40 hours for the EOCs, and maybe another 30 for the examples.
Depends on how well you know the material. If you know it pretty well then I’d say the above estimate is about right for the EOCs. If you don’t, then you will probably spend some extra time trying to track down explanations to answers that you don’t understand in the solutions. The examples should take you a lot less. I would estimate them at maybe 10-15 hours.
