MY SCHOOL

I STUDY AT "LA REPARACIÓN" SCHOOL. IT'S A NICE SCHOOL AND I REALLY LIKE MY SCHOOL IT. WE HAVE TO WEAR UNIFORMS.

You don't have to use caps lock.

Also, once you established that you're talking about school, you don't have to keep saying 

The last sentece is a bit disjointed. You should add more! Do you like wearing uniforms? What colors do they have? Does everyone at school wear uniforms :)?

Good luck!
