Source of GMAT questions

[VaibhavS720]

Hi,
I am looking for a reliable source of GMAT questions that gives me most accurate idea of the kind of questions that I am going to see in the GMAT WITHOUT ruining the official practice tests for me. Pretty sure I saw a few questions from your practice tests appearing in the GMAT Prep software, which ruins the experience of the official test, a big no no for me. An illustation or two are fine but want to know if Manhattan Prep uses the questions from Official gmat sources like question packs/ practice tests

You will never see one of our questions in the GMAT Prep software or vice versa—our problems are ours and theirs are theirs. No test prep company is permitted to use official questions in their own company CATs or other materials.

If something seemed familiar to you, that's because you learned how to do that "type" of problem and so you "recognized" it as something similar to something you'd seen before. That's a good thing—that's exactly why you're studying so hard!

If you are looking for practice questions that are the closest possible to the real thing, then look at officially-sourced problems. GMAC (the makers of the exam) guarantee that all current materials do not overlap—the latest OG books, the GMATPrep exams and practice problems GMAT Focus, the IR Prep tool, etc. (If you go back to an older version of an OG book, though, you may see a problem that has since been retired from the book and now appears in one of the online resources—so if you don't want to spoil yourself, don't look at older OGs. Also don't look at material posted for "free" that's labeled OG or official. That's all old material that people have copied—ripped off, basically—and put out online...and if you use it, you may see questions that you'll later see on GMATPrep.)
