I’m desperately trying to pass my CDL permit tests and this was recommended by a friend of my brother. Not owning any Apple devices, I bought a used Air 2 for $100, downloaded it, only to find that the Class A General test prep is identical to the Class A General test prep 2. This is the same pattern for all of the test preps. Additionally, all of the Brake test preps are identical. The question about the ABS warning indicator color is repeated in the Brake test preps 3 times, and this is only one of the duplicated questions in the tests. In all, there are possibly only 250 unique questions in all 20 test preps. I decided to pay the $1.99 upgrade fee to remove the ads and get “Full Access” to the test question pools (1000+ questions) and all of the tests (40+ tests). It removed the ads perfectly, but there are no additional questions or tests added … no “Full Access” advantage! The App Support link goes to a blog page for Infotech, a seemingly unrelated company. I am not able to gain access to leave a comment there, and my email to the one listed there goes unanswered. I cannot find a way to get a refund for my $1.99, and the $100 I spent for the iPad is a complete loss. I am VERY DISAPPOINTED and ANGRY. This is criminally misleading advertising at the very least. This experience only adds fuel to my distrust of Apple and Apple products. DO NOT BOTHER DOWNLOADING OR BUYING THIS APP, IT IS COMPLETE TRASH AND A WASTE OF TIME.
