Just die for the first time and the achievement will pop up.

After you receive your test, go to the door on the right of the table and click on it a few times until it opens.

Achieve score 100.

Get killed by Lunatic.
After you score some points, there's a chance that Lunatic will appear at a random place. He's scared by flashlight so make sure to avoid lighting at him. (When you hear him laughing it means he got away, so you have to wait until he appears again.)


Achieve score 300.




If you find this achievement hard to get, there's one trick to make it a little easier. You can pause the game! Try to set your camera, so you can see the test while you pause the game (like in the picture below). Now you can solve the problems without worrying about mannequins. Write down the answers. After you unpause the game, try to type your answers as fast as you can before a mannequin shows up.
