★★★★★Mar 19, 2023

Very helpful

★★★★★Sep 2, 2022

This is simply a demo of the full app with a limited 20 questions that do not change. I appreciate the full app may be worth what it costs, but this lite version is little more than a sales funnel.

★★★★★Jun 4, 2021

It was actually cool with the quiz

★★★★★May 23, 2021

Good practice

★★★★★May 12, 2021

Good

★★★★★Feb 10, 2021

Tried it twice and each time it recorded different answers than I gave... The 2nd time I was very careful to hit he answer I wanted and it still marked me wrong on 20% of them. Frustrating!
