Don

I'm taking the course in March (V5). My V4 in December was cancelled.

What of the self-study modules can be expected on the exam?

Boson or PrepLogic for examtests?

best regards,

John

I'm not sure if the self-study modules will be included on the exam as they're not listed in the course objectives. My CEH v5 class is next week so I'll make sure to follow up here and let you know.
