How to keep my timer, and health from one world to another

Hello, I am new to this program and I have to have a bit of trouble. basically, I am creating a maze game, and the objective is to collect all the blue orbs before finishing the game. The thing is, once you collect an orb it's supposed to take you to a question(world), and depending on how you answer that question it will either lose a bit of life or it stays the same if answered correctly. I have it all done but when the question is answered and it goes back to the maze, the whole maze resets(the timer and health reset). any idea what I should do? I can provide code if need be.

You must return to the same world. Using the new keyword will create a new object. If you have worlds called MazeWorld and QuestionWorld, in MazeWorld, you would use: 
Greenfoot.setWorld(new QuestionWorld(this));
In QuestionWorld, have: 
World mazeWorld;

public QuestionWorld(World world)
{
    super(600, 400, 1);
    mazeWorld = world;
    ...
}
...
// with the following line somewhere
Greenfoot.setWorld(mazeWorld);

OK ok with that being said I have a two-part question: 1: with the line of code you provided "Greenfoot.setWorld(new QuestionWorld(this));", can you put it into a method in the maze class that returns a variable that stores that instances of the world? So that we can access it in other classes? 2:what if the ...new QuestionWorld () is being called in an Actor subclass? Because of that line that creates a new QuestionWorld we have something similar already but it's in the smooth mover subclass that I have created.

Unnecessary. "this" IS that instance of the maze world when used in the MazeWorld class.
2:what if the ...new QuestionWorld () is being called in an Actor subclass? Because of that line that creates a new QuestionWorld we have something similar already but it's in the smooth mover subclass that I have created.
Then use: 
Greenfoot.setWorld(new QuestionWorld(getWorld()));
