The notes they gave me were very encouraging.
What kind of notes did they give?
They told me to work harder, stay at school and live a good life.
It's really nice to write encouraging notes for people. It could really improve someone's day.
I'm going to ignore them and not work on my grades like they have told me to.
I don't think you should be ignoring great advice here. You should listen to what they are telling you!
