No you don’t. Only if you have uploaded the official report which will show the "C" in all the lines. Otherwise it is impossible for them to know.
What if the school asks for the official report on admission? It will show you lied/ hid information. It is better to include cancelled attempts whn puting down a number
Booth anyways only take the highest score into account so not reporting the true number f attempts cn only hurt
To clarify you dont have to include exact scores from cancelled attempts but better to write you gave GMAT 3 times even if you are submitting only one or two scores
Why would they ask you the STUDENT report? GMAC sends a different version for the schools (and asks which schools you want to send) for this reason. Otherwise, your logic defeats the entire purpose of being able to cancel a score and not disclosing that event altogether
