I'm taking the GRE subject test and chemistry this fall and wanted to know if anyone has preparation advice? It looks like the best way to start preparing is going over text books and using the practice test posted on the ETS website. In later phases of my test prep I would like to do practice tests or questions so I can prepare for the pace I need to be answering the questions. I have looked into the prep books and judging by the reviews the books do not seem to be very helpful. Do you know of any helpful materials?
