Best of luck with your choice. I don't think anyone needs to take a skills test to help them find out if they have "the stuff" to make it as a pilot. Sounds like a cheap marketing ploy to "confirm" to a prospective customer they fit the bill to become a pilot. I wonder how many people they have turned away willing to spend 90K in the school because they didn't do well in the skills test?
For what it's worth here is my advice - if you have a job do the private license part time and pay as you go. It's a cheaper way to find out if it's something you really want to do - six months time once you have the private you can look at the next step.
