Well, I'm not quite sure. I want to think YES but it really helped me to get an idea of what I was going to face there so, I got some of the exercises down before attending the assesment.
I think I have good skills but it's an advantage to practice a bit. You need some time the first time to get into habit, and if you have already trained, you just need to apply your knowledge in the tests so, it's something you have to think about, depending on how do you feel in this kind of challenges.
If you are good, you'll probably pass as many others have done. If you hesitate or have any doubts, this software can surely help you to improve your skills.
cheers !!
