Another entry:One thing I wish I knewI found that, on any GMAT Forum, its key to understand the perspective of the person posting the answer. So much of GMAT Preparation and takeaways from sites has to be put to perspective in the learning process. E.g. A non-native speaker has to be extremely careful to distill only the information that is useful for his preparation when he goes through a native speaker’s review of products, answers and exam review. I think one of the reasons why Ron from
MGMAT is so good is he is able to cater his answers to any particular demographic and that just makes understanding problems so much easier.
