About the reading and listening section's score

[Comandante]

Hi all

i got barron's toefl ibt book and CD for testing, but i've a problem about grading my reading and listening tests. I mean, the points are differ with book and CD,
i do 27-28 correct answers in reading test and the book says it approximately equals to 21-22 points but in CD it's 17-18 points and also in listening part, i do 24-25 correct answers, the book says it's equal 22-23 points approximately but CD says it equals to 18 points. Is there any logical reasoning about this problem or does it change in different times?

As shortly, if i do 27-28 correct in reading section (totally 39 questions) and 23-24 correct in listening section (totally 34 questions), how many scores i get from these sections 'approximately' ? (i know Ibt's score calculation formule is unknown but any idea about that

Thanx

Hi Comandante, you should be aware that some questions might worth more than one point! Some questions worth 3 points! So pay attention for these questions. You usually encounter such type of questions at the end, so take your time solving them.

Another advice, study the types of question you might face in the reading section. This well help you a lot knowing what strategy to follow and of course if it worth more than one point :)

When are you taking the TOEFL exam?
Wish you good luck ;)
