This is a type of cheating for these certifications. That's why there's an exam to test your knowledge what you actually know. It's a professional certificate and AFAIK, there's an oath that before taking an exam, you should be true to yourself and there's no way that you'll cheat on these certifications.
It's okay if it's just like a review or study before the exam but, if doing this on the actual time of exam day, that's cheating.
I never told nobody needs to learn, we help people, who struggle the exam. Going to an exam without learning is not a smart idea..
We know what answers they will get and what trick questions there is. And that's the way we help the candidate.
Well, I understand your generosity but that's not the way it should be. Learners and students or professionals that wants to get those type of certifications should really pave their way in obtaining one and be prepared of it.
And in your case, as you've said that it's a 100% that someone will pass, this isn't the type of service that they should avail. It's a leak, it'll make them dependent on it and could take the certification and go out in the real world incompetent.
