I've gone through the 12th and 11th editions of the OG and was wondering if the 10th edition is too far out of date to use. I was looking for additional questions to practice and have a copy of the 10th edition.
No harm in going through. maybe some questions are not going to come anymore. But for practice, I dont see any harm.
You can solve the wonderful questions posted on these forums if you need more practice.
Also read the debriefs of successful GMAT test takers for additional resources.
