I have no idea if this type of question is appropriate for this part of the forum, but I am looking for help with the GRE. My two questions are: Does the test taker automatically have a 130 without answering any questions wrong and then points are added to the 130 as they are answered correctly? Is there a site that someone can look over my practice AWA responses, or do users here compare their practice responses? I hope the first question makes sense. I had called the test center to inquire about the way the test is graded and they said they were "not allowed to answer". I am also wondering if the GRE is similar to the SAT where not answering a question takes less points off than answering incorrectly. Any help is appreciated.
