how are canadian marks converted to GPA?

<p>Hello everyone, I am very curious about how the colleges convert marks from Canadian schools to GPA.
Is 90%= 4.0? </p>

<p>Thanks.</p>

<p>you can't really convert it . . . every school has their own way.</p>

<p>some schools have a scale out of 100, some have a scale out of 4.0, etc.</p>
