GMAT Progress Chart does not match OG 2015 review?

[JiroDreams]

I was trying to put my answers for the math diagnostic section into the Excel spreadsheet provided for the "GMAT Progress Chart" and it seems that the answers don't line up. The plan states the spreadsheet works for OG 2013 or 15 "Complete the math diagnostic test on pages 20-26 of the Official Guide for GMAT Review, (2015 edition or 13th edition)" but I don't believe this is the case. Anybody know if there is a different spreadsheet for 2015?

Thanks!

The spreadsheet doesn't cover the Diagnostic test, sorry.
You'll have to find the correct answers on the answer key.

Cheers,
Brent

Ah okay, thanks Brent. Day one it states: "Use the Answer Key on page 45 to determine your score, and use the Interpretive Guide to help gauge your current mathematical abilities. Record the diagnostic test results into your GMAT Progress Chart." Just a little confusing.

Ahhh, I see what's up.
You're confusing the Improvement Chart with the Progress Chart.
The Improvement Cart allows you to enter your responses for the OG practice questions.
The Progress Chart has a column for Diagnostic test results.
