This is a common misconception: that having seen GMAT questions before makes them useless, because you are already familiar with the questions and perhaps even remember the correct answers.

Repetition is an essential part of learning. There is nothing wrong with repeating the same questions over and over, so long as you learn something new each time--or maybe you simply re-learn a fact, concept, equation, strategy or rule that you had since forgotten.

Yes, if you're seeing questions more than once, then that ruins the questions from a score prediction standpoint, because you are of course more likely to answer them correctly on a 2nd, 3rd or even 4th try. However, building your base of overall learning is far more important than constant diagnostic prediction.

I agree with mcelroytutoring that practice the same question many times isn't a bad idea because we could learn something from that question. This way is the same as the way we practice something by doing it many times.

However, be careful to take the test many times. Take the same question many times is only good for practicing, not for estimating score. Once you see the OE of a question, you will remember how to solve that question. If you take any test that contains that question, you could remember solution quickly and select OA easily, or you could remember solution incorrectly and select answer choice quickly without thinking. This will do more harm than good.

I think that we should save available test for proper usage.

because SC test meaning and logic, if we do old questions, the questions we do before, we can not practice ability to realize meaning and logic on original choice and so, we loose ability to realize logic. this will harm us.

is that right?

to maintain our ability to justify meaning and logic, we need regularly do new questioins.

No way. You should definitely redo old problems. If you work on something once and never look at it again, you'll forget it almost entirely within a day or two. If you look at something repeatedly, you'll start to remember it for longer and longer. It isn't bad that you remember the old problems - you want to remember them! That's what studying is for - so you remember what you've worked on!

Hi ccooley,

Agreed!

Random, unrelated question: Do you have your ESR from when you scored V49, and are you possibly willing to share it? I've never seen a verified V49, so I would love to take a look--based on prior research, I would assume that you answered only one question incorrectly out of the 30 counted questions.

Also, what was your test date if you don't mind? I have a theory that Verbal scores of V49 and V50 are no longer possible, since yours is the only verified one I've seen. I've seen examples of 46, 47, 48 and even perfect 51 scores, but I've never seen a verified score of V49 or V50. (In fact, for a time there was a verified V50 on GMAT Club, but he got bumped up to a perfect V51 after the ESR revealed that he answered every counted question correctly, and GMAC was publicly made aware of this fact).

I have found quite the opposite actually. If you reuse questions strategically it can be quite powerful. The way to test if we have truly learned something is to expose our brain to the same information after a week or two, and test our thought process (not whether you remember which multiple choice to choose).

Do NOT reuse questions on the same day or even same week. However, if you flag questions that you struggled with and revisit them a week or two later, this can be a powerful method to ingrain learnings.

In fact, reusing questions is one of the 3 most overlooked gmat success strategies I recommend in my free course at Mind Over GMAT: https://mindovergmat.com/p/the-three-most-overlooked-gmat-success-strategies

Let me know if that does not make sense. Happy to clarify further. The GMAT is a game of pattern recognition and endurance. Use learning techniques to improve them both.

As yourself this question:

If you've "done" 100 GMAT questions before -- and you reattempted these 100 GMAT questions you've seen before -- will you absolutely and positively get every single question correct?

If the answer is yes - then perhaps these questions are "useless" to you. But if anything, you've reinforced your understanding and confidence.

If the answer is no - which is almost always the case for anyone preparing for the GMAT -- then that means there is still some value in going through these questions you've seen before.

You see - it's not necessarily the questions themselves that are of value to you -- but rather the thought process that you are forced go through that reinforces subtle thinking processes in your head -- even for questions you've seen before. These mental walk through is important and adds tremendous value to your reinforcement learning as you study questions you've seen before.

So do not not throw away questions just because you've seen them before -- even if you have supposedly perfect memory.

That said, if you are looking for extra questions - check out [url=https://www.gmatpill.com/gmat-practice-testsupplemental online question banks[/url] such as this one from GMAT Pill:

https://www.gmatpill.com/gmat-practice-test

Remember - it's all about thought process -- no memory - even the best in the world -- will be so good that studying an old GMAT doesn't provide value. There is tremendous value - even in GMAT questions you've seen -- so learn as much as you can and don't dismiss!

Focus, focus, focus.
