Economics student gives simple GMAT lessons

I am an Economics student from Italy, and my GMAT score is 730 (Q49, V40). When I first did a GMAT simulation I got a 600, which is proof that high scores are not accessible only to "gifted" people. The main goal of the course is to turn logic into theory, be able to recognize every type of question and and have a clear idea of how to behave in specific spots.
