**********************SPOILER ALERT************************

This achievement cannot be missed, as it's part of the story.
Once you get back to the Facility (chapter 8), you'll meet Wheatley with some turrets-cube hybrid. Just solve that test and then he will show you a stupidly easy test made by him. Once you solve it, he'll ask you to do it again. Proceed and the achievement will pop.

P.S.: here you can get the achievement "You made your point". The first time you get to this test, do not push the button nor press the pad, after a few minutes the achivemente shall pop.

P.S.S.: if you're going to rate down, please specify so I can edit the solution
