Hi,
well it depends on the University and on what you are interested in for instance an MBA rather a Ph.D
However, for Queen's Univ is the following
Quote:
GMAT or GRE Score
The Queen’s Full-Time MBA requires the GMAT score to be eligible for admissions, however, in special circumstances we will consider the GRE in combination with a strong profile. If you are seeking to work in the Finance or Consulting industry post MBA, you may be required to provide your GMAT score to a prospective employer. Therefore, we highly recommend that you thoroughly prepare for and write the GMAT.
Most students have GMAT scores in excess of 600. To register to write the GMAT, visit mba.com.
If you choose to take the GRE, you can use the GRE Comparison Table for Business Schools to calculate your equivalent GMAT score.
The competitive recommendation is to have a GRE score of 315+ on the combined verbal and quantitative section.
Please send us your official GMAT or GRE score, as your file will not be reviewed until we receive it. We cannot accept photocopies or faxed score reports. GMAT and GRE scores are valid if written within the last five years. You may arrange to have the official results sent directly from the testing service organization. You will not be penalized for having written either test on multiple occasions, as we take the highest score not necessarily the most recent.
Official score can be sent to Smith School of Business under the program name Queen’s Full-Time MBA using the following test codes:
GMAT: Q21-QZ-68
GRE: 4170
