@Hey GRE Takers I have the following questions, please help me. 1. Is the AWA section always first or there are chances of Quants/Verbal coming first ? 2. I heard there have been questions asked from Normal Distribution. Can you post some sample questions & solutions here. 3. With this OLD GRE, is it valid for 5 years or just till spring of 2011 ?
