ICON+

I found the ICON+ GMAT prep course very helpful as an exam primer. The course goes into substantial detail when it covers the relevant topics, which was good as I needed a refresher following a few years of work. The teacher was also professional and capable of fielding any of the (many) questions that the class had. ICON+ also provides 4 mock GMAT exams and a large repository of practice questions consisting of thousands of questions organised by topic, which should satisfy the training needs of most GMAT students. An added bonus is the availability of tutors throughout the week should we require personal attention to overcome our weak areas. During the course, I missed a couple of lessons, but managed to come down during the week and successfully caught up with the rest of the class.
