I think it needs shorter practice test, few of the practice question are on the real test.

By Michelle Acker on 6/16/2025

This gave me confidence to attempt the main exam.

By Martin Vogel on 11/17/2024

you have an error in one of the answers. You ask what the DPMO is - the correct answer is 80 but you say it is 50 (the explanation in the response is calculating correctly to 80)

By Geng Liang Chong on 8/7/2024

By Hoàng Thắng Bùi on 5/10/2023

I personally think the 10 Warmup Test need to be for free before anyone can decide to purchase the course. Anw, thanks, the course worth the value we spent.

By Martin Ramirez Olivarria on 4/12/2023
