Because when there were only 2 legendaries the drop rate would need to be low . <| sep |> I also never ever heard of that in my life , and I have asthma ever since I was 6 years old . Is there a relationship between ME and asthmatic ppl ? Lol <| sep |> Did you make that up ? <| sep |> Or a Screech Owl . <| sep |> My parents are ones , HELP ME . Its impossible to have a logical and understanding conversation with them . <| sep |> So this isn ' t by any means universal , but I have one course I ' ve taught now to just grad students , mixed grad and undergrads , and just as an undergrad course . The main difference for me is how fast I move , and how much ' spoon feeding ' I do . I don ' t do any homework or scaffolding in a grad only class , and probably cover about twice the material . I also assign more primary literature , and expect students to read and analyze it without much help . That said , I also usually do fewer assignments at all , and grading is less crucial for the grad class . I don ' t work example problems in class much , and expect that the students can apply concepts we cover to new areas . The other big difference is how much background I can expect all the grad students have a full BS , and I can assume a lot of background ability , and just cover new material . For the undergrad only class , I cover material slower , start slowly on papers , and we work problemsexamples in class . We also discuss papers in class so the students can get a good feel for how to read and analyze them . There are more assignments , and grading is in general more important . I can ' t assume certain levels of math background , and find myself covering a lot of basic material not directly related to the class in lecture . So it ' s not that grad classes are harder , they ' re just different . If you ' re self motivated , they can even be easier . The other major difference is in what class prep I expect . In a grad class , I expect readings to be don before class by the vast majority . I ' d only expect about half my undergrad class to have done the same , realistically .
