What does the COR Score mean?
One consistent scale makes different publishers’ ratings easier to compare. The original review still tells you why a critic reached that verdict.
Read our scoring methodology →Scale conversion · example

An illustration of conversion, not this product’s rating.
Check the match
Identify the exact model and the version reviewed. Check the manufacturer code, configuration and supplied accessories.
Compare on one scale
Convert usable ratings to five points, count each publisher once and give each critic equal weight.
Require three critics
Show the average to two decimal places after three distinct critics. Otherwise display tbd, keeping individual reviews visible.
Find the best fit by considering the score alongside the critic count, review dates, tested version and the strengths that matter to you. Eligible model-level reviews identify the tested configuration. Reviews of different hardware are shown separately and do not enter this product’s COR Score.
