Hi saviofernanz.
If I understand correctly, you are asking whether, in preparing for the GMAT, one can find and solve questions that are rather similar to any question that one would see in the quant section on the actual test.
If that is indeed what you are asking, for the most part, the answer is yes. The formats of the questions that appear on the GMAT are fairly predictable. So, if you do enough practice questions of enough types, in your training you will see questions that will be rather similar to almost every question that you would see in the quant section of the actual GMAT.
At the same time, since there are infinite ways to vary the way in which concepts are used in questions, the questions that one sees on the GMAT will generally not be exactly like ones that one would see when preparing. They may be quite similar to questions one has seen and use the same concepts yet employ twists somehow different from any one has seen.
Also, sometimes quant question writers come up with questions such that, while answering the questions requires using only the concepts that people commonly use in answering GMAT questions, the questions are somehow quite unique and may not look like anything one has seen in practice. So, in the quant section of the GMAT, one might see a question or two that are somehow rather different from any practice questions one has answered.
Yes, actually this was my Question.
Thank you so much for the explanation
