I have been wondering about his for quite a while...needed to get it clarified
For students like me (INDIAN) who are to appear for tests in addition to the GMAT (like the IIM CAT-2010), some of the topics in QUANT are very advanced as compared to those that appear on the GMAT...
For eg: In Geometry, there might be certain theorems like the Basic Proportionality Theorem etc. which aid problem solving...
However, in the GMAT I believe the stress is not on a lot of theorems and formulas, but general problem solving..

So lets say on the GMAT, I get a DS question asking me to solve a particular problem on, lets say, Geometry...and I, being an Indian student, know that it can easily be solved by using the said theorem and suppose with that knowledge I get a answer B ( by finding that it is sufficient to answer the question with statement 2 alone ).

Now it is possible for another student, who knows nothing about the above mentioned theorem ( has never learned anything of the sort in his entire prep), solves the DS question and gets an answer C ( that is by using both the statements 1 & 2 ),

I have taken Geometry as a topic only for stating an example. It might occur in other topics too.

My questions are -
1) Can such a situation happen on the GMAT?
2) If it does, then what is the solution?

No, this can never happen

All the extra theorems you learn will at best help you get to the answer quicker (very rarely have I even seen that), you won't ever get a completely different answer ... math is math ... knowing a few extra theorems doesn't change the end result.

Hi Shrouded, thanks for the clarification... :-D
What I basically wanted to question here is the scope of study on GMAT...and my doubt was over DS questions only (citing the above reasons) ...not problem solving ones...

Cheers,

Well, if you are studying for the CAT anyway, then the extra knowledge will only help.

But as such the "scope" is less. And again, PS or DS, what I said is still applicable. At best, you might use a concept to get to the right answer quicker once in a while, you'll never to get to a different answer than someone who doesn't know it.

Totally agree with above commments. GMAT wont frame question where extra quant knwoledge will help with answering questions. If I remember correctly... trignometry is not mentioned in the OG but it is very easy to learn and helpful in answering questions..
