Jun 27, 2008 Just to let you know, I go to Kaylim and they do not "teach you how to pass an EC exam." Lunah is incorrect. I stand corrected! But do they teach according to the EC curriculum, or not? That's what DLS does, from what I've heard from students who used their services. Kaylim sounds similar from their description.
