So many mistakes

I began the first test and discovered so many mistakes. The review of the anatomy section states that the crural region is the calf, but when I took the test and chose the answer, crural, for the question asking what the arrow was pointing to (it was pointing to the back of the lower leg) I got the answer wrong. I clicked on the little box that said "why was this wrong?", and it said that the crural region was the front of the leg! The test also asked a question about the anatomical position and after I got the answer wrong and clicked the "why was it wrong?" box, it said that the correct anatomical position was with the palms facing posteriorly! I stopped right there. How many more mistakes are there in this app? I want my money back

This is the worse app about Anatomy and Physiology
