@soheyl. I was referring to business schools' OM programs and not IE programs. Seems like some schools accept only the GRE for this area and a few others prefer the GRE over the GMAT. Below are a few examples I was referring to. A few others state that there is no min test score and that its only a component of your application. But then again the average v for those is about 550. MIT Sloan - "Those applying to Operations Management should submit GRE scores only". "There is no minimum GMAT or GRE test score required, although the faculty are most interested in applicants with the highest quantitative scoring."Wharton (OM)- "Although there are no absolute thresholds for admission, students who are admitted generally score on the quantitative GRE or GMAT in the 98th percentile or higher, have a high GPA from a prestigious undergraduate institution (e.g. 3.5 or higher out of 4.0), three outstanding recommendations from respected academics and well written personal statements." Stanford - "Operations, Information & Technology: the GRE is preferred, although the GMAT will be accepted."Tepper - "The Tepper School of Business faculty who review applications use the test scores as one component in the overall evaluation of an applicant's file. For the more technical areas, a high quantitative score sends a positive signal about the applicant's ability to handle math."Hopefully I get enough time to prepare for retaking the GRE ( between my full time job and the new GRE format). Else I might just give it a shot with my present scores.
