We are very sorry to hear that but certainly there is no shortcut to success and we never gave a 100% guarantee that everyone who takes our exam will pass the actual exam. Since you have failed the exam so we strongly recommend you to not give up and start over again. First go through the exam prep guide very carefully. Then try to identify the weak areas and cover the deficiency with the help of these resources; • Tableau provided free video. • Tableau provided help book. • Practice exam questions. It is natural anyone can fail the exam for the first time even if he was well prepared but no one should lose hope and start again and keep trying until you succeed.
