When do I have to pay?
One of the best features of GTA is that it allows you to start the course for free. All you need to do is just register and get started. It is only after reaching the end of the free trial that you will need to complete the payment step. You get to pay only when you are satisfied.
Once your payment is done, and you have completed and passed all the assessment components (online and verbal), you can download your Certificate/Statement of Attainment from My Courses page
