good
Quite interesting. Knowledge Booster
If you're looking for a free app, don't bother. Charges after like 3 out of 40 practice tests. Might as well just charge you from the start.
Great app, passed my test. I use few apps, 1 app was to easy, but after going through this app, I learnt more. App keeps a record of all wrong answers, helping to go through. Highly recommended
I completed all the questions in this app and passed the test in under 3 minutes! Prep time for me was two weeks. For anyone preparing to take the test, my advice is to work through the entire handbook alongside the questions in the app for each section (do this with the answers). Once you’ve covered everything, focus on the practice tests. Complete all 140 sets (no answers), and by the time you reach set 140, you should feel well prepared and confident going into the test. You’ve got this!
