Nibbler has a very good point. A lot of students have it banged into their head that they must set up a circuit, blah blah... if the engine fails, which can sometimes be completely the wrong thing to do. All he wants to see is you put it safely on the ground so practice a few scenarios with your instructor, best field being directly in front of you, how much alt you lose doing a 360 glide turn etc...
My PPL test was as mentioned above - simply a requirement for a competent, safe flight. I made mistakes, most people do, but nothing dangerous.
