This app is a fairly helpful revision tool for the inspection exams. However, it is let down by poor grammar, rendering some of the questions confusing. Some questions also give the same answer more than once as an option. Once answered, the current question disappears automatically without giving the user the chance to review any incorrect answers. As such, this app could benefit a "Next" button. The scoring system is not reflective of the system employed at TWI. Each exam paper requires a 70% or more to qualify as a pass. This app scores 20 points for a correct answer and -5 points for incorrect answers, with no accumulation on progress, or a clear indication of possible scores. The "I" (about) button displays a black screen with no legible information to read. The support link in Google Play leads to a home page from which no other access is attainable, effectively a dead link. Finally, the option to show an explanation does nothing on my device (Galaxy Note 8). There is no clarification or explanation displayed at all. But this is hardly surprising as, at the time of writing, there has been no update in two years! I offer a very generous 3 stars.

Im enjoying the app, but it seems to be just bringing up the same questions pertaining to each category, more variation in the questions would be excellent.
