Lot of prep companies/tutors are willing to help students. What am suggesting here is students can make certain requests for tools/ study aids and the prep companies can chose to assist students.
For example - There is no tool out there in the market for error log
of: GMAT Prep Question Pack1 - with reference to the question number in the GMAC format QDS13682 - it would take significant time for a student to develop it. Such a tool can be used for a cross reference without copying the entire question.
It's easy to say you can't do it , you are not good enough. It's much harder to step in your shoes and achieve the improbable.
