I've always been taught that revising involves checking for spelling, punctuation, and grammar. Basically any kind of improvements. Is this one of those questions where you check all that apply? Revising also includes making sure you have stayed on topic and gives you the chance to remove things that may not really apply or add other things that may have been left out. It's where the writer truly polishes everything up.
I hope this helps.
Hello there ^ _ ^
When my sister and I were very young, we believed that we could dig a hole to China, the antipodes of our backyard.
I hope this help!
This is how I would write your thesis. "Should kids be allow to bring their cellphones to school? I believed they should, because it's necessary for kids to be able to communicate with their parents in case of an emergency. In New York City, their policy of banned cellular devices will be reversed and students will be allow to use their devices freely. However, will other counties like New York city be as open minded and allowed the usage of cellphones?"
