Spoilers ? ! just kidding I watched it this morning . <| sep |> The moment you started asking about grains . <| sep |> Neary for some can be extremely boring , if you ' re not fully into the subject matter you ' ll probably find yourself skipping a few lectures . However , the way he does it is that he gives online quizzes that are open book and unlimited time with unlimited tries ? that are worth 20 % of your grade . His reasoning is that these quizzes are to help you learn , not to test you . As for his 234 , there ' s a lot of reading , 3 books worth , but they ' re not textbooks , and it makes for good toilet reading , very consumer friendly . As long as you enjoy reading , and you keep up with the assigned chapters there should be no problem . The math introduced in the course is very optional , as all exam questions are short answer writtenessay questions . However , Neary was a slightly hard marker when I took him , his first time teaching the class I think he claimed that , but in the end , he realized he was marking us a bit too hard , and scaled me from a BB to an A . For exams , be prepared to be extremely thorough and write until your hands cramp if you want a good mark .
