Magoosh Techniques are Good

Magoosh Math offers great videos and a variety of techniques that are different from those in Manhattan GMAT prep books. Given the price point and the practice question bank, it's definitely worth the price. Just note that their complimentary PDFs outlining Math aren't as well organized or thorough as Manhattan's Strategy Guides. Some of the videos may leave more to desire because they're short and to the point without additionally expansion on some of the techniques used.

I also noticed that their practice questions generally relate to topics Magoosh covered in their videos which can limit the the mimicking of real test questions.
