You state your thesis in the introduction and then you rework your thesis in the conclusion based upon the arguments you made in the supports.

So it should look like this.

Intro/Thesis

Argument 1 for thesis

Argument 2 for thesis

Argument 3 for thesis

Conclusion: in the conclusion do not simply just state the thesis again, you must rework it so you are proving it somehow.
