I am preparing GMAT for a while, started before the IR section was added, and since studying is going awesome, I am close to the end of the journey. Naturally, it will be important for me to score well on the IR section. My question is going to be kind of silly for most of you but I am still going to ask to check
The thing is, I do not have 13th edition of the GMAT book. I have OG 12th
Edition along with MGMAT 4th Edition Guides. I will order the MGMAT IR book soon (Kindle version because I can get the access as soon as I pay). Do I really need to buy the OG 13th
Edition just to have the problems to practice or the MGMAT IR guide will be sufficient?
