Best online tutorial for GMAT Verbal

I took the eGMAT verbal prep as I wanted to improve my verbal scores. I personally feel that eGMAT verbal is the most comprehensive and effective online learning tool. The course is designed in such a way that it covers the gamut of questions asked in a GMAT exam and classified in different categories according to the important concepts being tested by GMAT in these questions. This way the course helped me identify the areas where I lacked understanding of concepts and where I needed to improve. The quality of questions asked in the tutorial is very good and develops stronger understanding of concepts. Also the tutorial is organized in a manner in which one for accessing a file one has to complete some mandatory concept or application files, as these concept or application files are prerequisite to the file. This way the tutorial clearly marks the flow in which one should approach his learning. I believe this is the best online tutorial and the best option for the one's who cannot attend live sessions and who wish to improve their GMAT scores.
