Just finished working through the verbal sections of the Princeton books in exam conditions. Across all question ranges and difficulty levels I was getting close to 80% accuracy. Recently I started working through the Magoosh
practice questions online and my accuracy has plummeted to below 40%. Part of me thinks the change might be due to the fact that during the text book questions I had been activity marking the text and underlining, something that you cannot do in the real exam. The question format of both appears relatively similar. Any other explanations for what might be the cause?
