How do they score the following questions?

[wagawaga]

i dont understand how they score the following TOEFL listening questions.

1. Yes-No questions. The question generally asks for things like "does the following support the hypothesis?." Then you get a table with about 5 different sentences and you have to either check "yes" or "no" on whether the applied sentence supports the hypothesis or not. My book tells me that these type of question can give up to 2 points. How many do you have to get correct in order to get 1 point?

2.Connection Questions. Connection problems ask you to show relationships on a chart. For example, if i read a passage about bugs, it will ask something like "indicate whether each insect below refers to a model or a mimic (types of bugs)" then there will be a list of bugs and i have to categorize them to either the model section or mimic section. Book says they are worth 4 points but does not elaborate how much is worth one point, how much correct is worth two points and so on.


Thank you everyone in advance
