Keyboard Challenge description

If you like nerdy and challenging games, this is a treat for you.
The rules of the game are simple: Finish typing all challenges displayed on the screen within 30 seconds. But here's the catch, you won't be using any keyboard you have on your phone. You will be trying to complete each stage with a different keyboard.

You have 5 levels to complete the game. Each level is more challenging than the one before. Levels have a maximum score of 3000.
So how fast can you type?

*Please note that the challenges are not case sensitive. So you don't need to type upper case letters.
