Revised GRE® Practice Test #1

After you have taken the practice revised General Test, it is time to evaluate your performance. Because the new Verbal Reasoning and Quantitative Reasoning score scales for the revised GRE General Test will not be available until November 2011, we are providing estimates of your performance on the Verbal Reasoning and Quantitative Reasoning measures based on the previous 200 to 800 GRE score scale. These estimates should give you a general idea of how you might perform on the revised GRE General Test but they are not precise predictions of your future test performance. The score ranges provided should help guide your test preparation.

Analytical Writing Measure

One way to evaluate your performance on the Issue and Argument topics you answered on the practice test is to compare your essay responses to the scored sample essay responses for these topics and review the reader commentary for these sample essay responses. Scored sample essay responses and reader commentary are presented in the separate document, "Analytical Writing Responses and Commentaries" (GRE Practice Test 1 Writing Responses.doc or GRE Practice Test 1 Writing Responses 18 point.pdf) for the one Issue topic and one Argument topic presented in the Analytical Writing sections of the test. The final scores on each of the two essays (Issue and Argument) are averaged and rounded up to the nearest half-point interval. A single score is reported for the Analytical Writing measure. You should review the score level descriptions in the document "Overview of the Analytical Writing Measure" (GRE Overview Writing.doc or GRE Overview Writing 18 point.pdf) to better understand the analytical writing abilities characteristic of particular score levels.
