Hello,
Apologies if this has been covered elsewhere. Is there a crosswalk showing which problem crossover between the old and new versions. Would be very helpful. I am using Magoosh and they have their explanations for the older version.

Thanks!

There are a number of resources out there that give the changes from OG 13 to the 2016 edition, but not (AFAIK) from OG 13 to the 2017 edition.

An easy patch for this would be to go to Google Books, load up the new OG, then search the text from the question you're working on. The search result will show you the # of the question in the 2017 edition, easily giving you the number key for any problem you're working on.
