Helo effect, Bluff questions,pool

[arzgol]

1) Scoring is objective and reliable (e.g. no halo effect) .Is it a hallo effect? Does it mean parents ask a teacher for a grade?

2) Students are not able to "bluff" or "pool" answers. You can ''bluff'' somebody but how can you bluff answers? Is it mean to guess. Does pool here mean to collect ?

Thank you so much answering my questions.

N.A.T.
1) "halo effect" is correct Halo effect - Wikipedia, the free encyclopedia
2) Yes, pool means to collect in this context. I am unsure about bluff here. I think it means to cheat in this context.
