¿Qué Comiste tú el sábado?

Okay i need someone to translate this to spanish for me . i would use google but it aint that accurate. my goals for this semester are very cliche. just like any other student i would like to be a straight a student and make the honor roll by the end of this semester. so far im doing really well following my goals. when i achieve my goals my family would be so proud of me. its honestly a good feeling when you do something big (:
