***WARNING: SPOILERS AHEAD***

1: Pit Boss

All it says in the description is "Show that pit who's boss", so let me explain. At the chapter "This Is The Part Where He Kills You", you have the opportunity to escape the clutches of Wheatley. Once out of range for his crushing walls, he'll ask you to go back to him. Simply walk to the edge of the walkway to where you were once trapped and listen!
Wheatley will try to persuade you to jump into the pit. You can sit and listen to his fabulous prizes at the bottom or simply jump.
So show that pit who's boss!

2: Preservation Of Mass

Break the rules in Test Chamber 7, easy enough! During the second part, you'll be told after solving the puzzle that the wall that destroys all matter stolen from the test chamber is broken and not to take anything. So obviously you HAVE to take something!
When you start this Test Chamber, place the cube closest to the edge above you while keeping it pushing the button. Once you get up on the ledge, crouch and crawl as close to the button without falling off, then pick up the cube and carry it out with you.

3: Schrodinger's Catch
20 Gamerscore
This one askes you to catch a blue cube before it touches the ground. This one is a little tricky, but quite simple once figuring out the trick to it.
In one particular test chamber, the cube is stuck behind a glass container, and the only way to free it is to cover it in blue gel. Once the blue gel starts to pour, instantly turn it off, a drop is all you need or else its gonna get complicated. Wait for the cube to smash one side of the glass, run over to it and wait.
The rest is up to you!

4: You Made Your Point
10 Gamerscore
Simply refuse to do a test with Wheatley in charge. This will be the first test right after GLaDOS uses the paradox on Wheatley. Once the lift takes you up to his test chamber, walk off and stand still until the achievement pops.

5: Portrait Of A Lady
10 Gamerscore
While testing through Cave Johnsons old tests, you'll find yourself in the chapter called "The Reunion". Right before the last test chamber in the chapter, you'll see a small stairway behind a closed fence. Luckily, there's a white wall inside the room. Simply shoot inside there, and there's the human form or GLaDOS, hell Caroline!

Well, hopefully these give you a bit of an insight into how to get some easy achievements. I bet if I made videos of these, these tips would be easier to make sense....
Thanks for reading!
