Starts from the ground

I purchased the 12 month access pack to Magoosh. I had also used this for my SAT and knew of its quality

Here is my review

It starts at fundamentals so if youre someone who has been out of college/school for a long time. This serves as a good refresher course.
It has very nice questions that are similar to the official. Clear and concise explanations

On the other hand, it starts at such a basic level that it skips over the tips n tricks that you may need to swiftly move through the exam, which can be supplemented with webinars of other companies as to not invest more money or youtube
The number of questions and mocks available is also not that much.

But again at its price point, it offers a structured approach to gmat which is the main reason i went for it with a decent selection of questions to practice.
