IR - score and strategy

Hi folks!

Please, your help with these two doubts:

1. In the IR section, how different are the scores of the GMATPrep from those of the real GMAT?,

According to some students who have scored 8 in the real GMAT, they didn't answer all the questions, so they had to guess in the last 3-4 questions. Therefore, to get that score, probably they answered correctly from 6 - 9 questions.

However, when I have practiced with the GMATPrep, I answered the 12 questions with 7 answers right and got a 4 in the score. Ok, I didn't expect a 8, but probably a 6 or 7, considering the fact that in the real exam these guys got a 8 with 6 to 9 answers right.

Also, I don't think that probably they answered questions that provided a higher score because, according to an Official GMAC representative in other forum:

"The different questions types are not weighted differently. In other words, table analysis questions, for example are not necessary of a higher or lower difficulty level than any other question type. The IR section does include questions of varying difficulty within the section, and your score is based on how many questions you answer correctly (...) You must be able to answer the higher difficulty questions correctly as well as the lower difficulty questions to perform well on the IR section." [/i]


So, what do you think?

2. In this sense, I think that my strategy to take that section would be:
- To skip 3 questions, because it's almost impossible to solve the 12 questions.
- Those skipped questions would be of the Multisource Reasoning type (MSR), because they consume too much time and wouldn't provide a higher score. It's better to invest time in 2 graph analysis questions than in one MSR question.

My only concern is that there could be more than 3 MSR questions in the real exam. There I could be in trouble LOL.
Other doubt is whether the section will show a experimental question.

So, what do you think about my strategy?

Thanks!
