    Great place to do your Security training, did mine all online, First Aid with Sherif which was great. All leaving One star out as you can't download course material or print it out as I'd prefer that except of having to carry … More my laptop around everywhere. All in all a positive experience. Also for future students if you guys can throw in a couple of practice tests that be great help. Thanks.

    OEIS does a great job at providing and teaching individuals an original yet necessary take on all information needed to pass Ontario-standards-meeting tests. They offer optional exams to complete prior to the final exam which really help … More studying and further implement understanding of knowledge. I recently passed the Private Investigator course and could not be happier with the service OEIS provided.
