CDL Permit funktioniert nicht

You need to buy a lifetime access (paid once) or subscribe to get access to all features (such as random exam, timed quizz, incorrect questions review, bookmarks and etc. ), courses and questions.  Obtaining a CDL means you have the skills and capability to operate a specialized vehicle, whether it is a commercial truck, combination vehicle, school bus or a fuel tanker.  Subscriptions are auto-renewable and are billed at the rate and period selected depending on the subscription plan.  Subscriptions can be managed and auto-renewal can be turned off in Account Settings in iTunes after the purchase.  Users’ accounts are charged for auto-renewal within 24-hours prior to the end of the current period.  A CDL is a driver's license that allows you to operate commercial motor vehicles.  The cost of the purchase is charged to your iTunes account.  The rules differ for each state and our app collects them all in a single and convenient package!  Ace your CDL exam with a great level of self-assurance!  Any unused portion of a free trial period, if offered, will be forfeited when the user purchases a subscription to that publication, where applicable.
