Looking forward to study at the University in Yekaterinburg

Hi, I'm a newcomer to this forum, and I don't know if this is the right way to ask about this, but, I'm planning on studying University in Yekaterinburg, at the Urfu, but I have a doubt, I had some personal troubles and couldn't finish high school, my only option to finish it now is a knowledge test that would give me a certificate equivalent to a high school diploma, and is validated by the Public Education Secretary of my country. Being an adult education system, do I still have the chance of being accepted at this university? I tried contacting them by mail, but they didn't answer back, so I thought I could find an answer her, hope you can help me.

BTW I'm currently living in Canada, but this certificate I'm talking about is Mexican.
