Bachelor degree with a minimum GPA of B (3.0 on a four-point scale, or 4.0 on a five-point scale) to apply. You must have a strong background in mathematics and physics, and, with rare exception, familiarity with an engineering discipline. You should score in at least the 80th percentile on both the Quantitative and Analytic sections of the GRE - this is not a requirement, simply a recommendation. On the TOEFL, you must score a minimum of 100 on the internet-based exam.
