Checks all the boxes!

I agree with the general belief prevalent among GMAT community members that Manhattan is a very good material for GMAT preparation.

I bought 12 book set from Manhattan GMAT about a year back and was amazed by the level of detail in both the verbal and quant segment. The level of detailed analysis presented and the comprehensive explanation is great. Even the quant supplementary material which has a fantastic set of advanced quant questions. This is supplemented with easy to use tips and strategies.

I found the tests that were offered by Manhattan GMAT to be a good indicator of scores. The MGMAT tests are pretty close to what the actual tests were.
