Let's start another round of speculation here, unless someone knows the definitive answer....

Let's assume this: Difficult Question with the following answer choices

a) rubbish

b) Gmat trick

c) rubish

d) fancy Gmat trick

e) correct answer

Do you guys suppose that the scoring algorithm might harm you more for picking answer a) over answer d). I could see this being the case, it in my opinion, would partially contribute to why people could score an 800 with multiple wrong answer. The wrong answer these people had were not 'straight out' wrong, but maybe in a complex math problem one forgot the final step, but was on the right track, thus the algorithm gives you 'partial credit'.

What do you think guys?

Sample Question I have in mind is this:

A dog trainer has 13 dogs, 8 of which are German shepherds. If he trains 5 dogs in a training session and at least 4 are German shepherds, then how many different combinations of dogs might he train at any given session ?

a) 10

b)231

c)336

d)350 (8C4*5C1)

e)406 (8C4*5C1)+8C5

OA is E, however answer D is representative of the right thought process, but the reader fails to take 'at least' into consideration. Thus I am wondering whether there may be something like partial credit. This question is adapted out of the most recent book of a company that just bought another company if you know what I mean

Any thoughts?
