In an earlier post, we reviewed GMAT apps that can be useful in your studying. We found more and more apps popping up on the web during our search, so we felt it would also be helpful to tell you which ones aren't worth buying or downloading. Keep in mind that even well reviewed apps can be of limited use depending on your situation. All of the comments below are strictly our opinions based on extensive experience teaching the GMAT and analyzing actual GMAT questions to become more effective tutors.
Kaplan GMAT Flashcards
Although Kaplan is a very reputable test prep company, this app is a bit of a letdown. The app provides questions like "What is a participle?" that won't really help you identify a participle on the sentence correction questions. No actual practice questions are included in the flashcards and, after a few rounds, the flashcards won't be helpful anymore. Anyone who has already started their studying will find this app too basic to be useful.
GMAT Connect by Watermelon Express
This app is produced by a startup company that has been profiled by BusinessWeek since it was started while it's founders were completing their MBAs. Although the app seems to have a lot of features, we're skeptical about the authenticity of the actual questions. Writing good GMAT questions that simulate those you will see on the actual test takes analysis. Leading test prep companies, such as the Princeton Review, have spent hundreds of thousands of dollars on researching techniques and developing the most authentic test questions available. We just don't think a startup would have thoroughly analyzed and created questions that will help you improve your GMAT score. More practice isn't necessarily better.
GRE and GMAT Vocabulary Builder
Vocabulary is extremely unimportant on the verbal section of the GMAT. Two-thirds of your questions will be based on logical reasoning rather than word knowledge. The other questions are grammar based. While increasing your vocabulary is always a good idea, don't waste study time with it.
