Commas and Full Stops New

This is my friend Cindy she goes to university

She made many good points however I don't agree with everything she said

Cleo and her band will be playing. At my school next Friday

John, and David are working on a project

I will buy a cheese cake, and hot chocolate.

First I will go to England then I will go to Ireland then I will go to Scotland

My favorite food, is definitely pizza

I want to have a big home. With a swimming pool

She was late for class, because her alarm was broken

She was late for class but she still felt happy about winning the singing competition
