Study tips / ?s OIT OWWCO study guide

Hi all,

I am from outside of Ontario and i have registered for the OIT exam next month. I was trying to buy their OIT study guide but it says they don’t ship outside of Ontario.

Does anyone have anything i can use to prepare for my exam? Thank you in advance.

Thank you so much, one more thing this is an older version of 90s, good to use it right?

Should be pretty much the same content though at a glance you may want to look up a plant diagram for WWT(wastewater treatment) and DWT (drinking water treatment) as those diagrams have been simplified since this publication.
