Typically, how long did you guys study for the exam? I understand that it depends on one's memory, concentration etc,but wanted to get an idea. I'm preparing for the October PE power exam and there are only 6 months left. While some people say they studied for only 3 months and passed, I wonder if they are boasting. I have a huge work assignment coming up and would be dedicating two out of my 6 months for that, so in reality, i will have only 4 months to study for PE. I want to give only one shot, my best shot for this exam, as it's both expensive and stressful. Anyone out there who thinks that their 4 months preparation was sufficient? Please share your thoughts and study habits.
