Thanks PrepCast! The simulator helped me with the types of questions that were given and the test taking aspect - reading questions for four hours! I first started getting 65% on the Simulation Exams and quizzes, and worked my way up to 75% - 80% the days before the exam. I would recommend going through as many questions on the simulator as possible, and spending time to review the questions.
As an online test taker, I experienced quite a few technical / computer issues with Pearson's though I had disabled my firewall and ran the system checks a few times leading to the exam. For the test and possible technical issues, I would recommend mentally preparing yourself for this. I went into the exam expecting to encounter technical difficulties, and so I wasn't distracted when they actually occurred.
In any case, you can do it! It is possible! I didn't know if I passed until the screen showed "Congratulations." And on top of that AT/AT/AT!
