Form my interactions with various instructors, I have come to the conclusin that Horacio is by far MGMAT's biggest asset!!! He is very capable of explaining comlicated problems and simplifying them for students. I have been using Horacio for a while for both verbal and math and he is just an amazing individual. He has helped boost my confidence in the test, improved my understanding of math concepts, and provided me with direction for improving verbal. I highly recommend him to anyone serious about his or her GMAT.
Thanks to Manhattan GMAT for hiring such a talented and smart teacher.
