This sentence should be very clear. Colloquial expressions may be misunderstood by a reader, so don't use them. This mistake shows that the writer is not sure about what a sentence really is. There are other mistakes like these in the rest of the essay. Everyone makes mistakes when they write quickly.
Good writers take the time to go over what is written and correct mistakes.
Your writing will show your best skills if you take the time to plan what you say and review it to make any needed corrections. If you take the Official GED Practice Tests on your own, we recommend that you ask an adult education teacher to help you score your essay. The self-scoring answer sheet for Form CC of the Official GED Practice Tests has an essay scoring guide. See order information on the back page of this Bulletin.
