I'm working with the MGMAT 4th edition and wondering whether to get the 12th and/or 13th edition of the Official Guide, as the 4th edition MGMAT refers to questions in the 12th edition of the OG.
I came across margarette's post "Breakdown of Official Guide 13th
edition vs 12th edition" by , which was quite helpful (sorry, I'm not permitted to post links yet as I am still a new member). The post includes a conversion table. I wonder whether the table is reliable now since there were quite a few errors in the beginning?
Would it be worth to get both the 12th and 13th edition? Or should I just get the 13th and use the table above to track the questions and omit any questions that were dropped in the new edition?
Is there another source which links the MGMAT 4th edition questions to the 13th OG?
Thank you very much in advance!
