Premac said it right, it's all about practice. His advice is spot on. Time yourself only after you have mastered each section. When you take your practice tests on CDP, focus on understanding every question. Figure out why each incorrect answer is wrong in addition to why the correct answer is right. This will help you build your speed when you start to time yourself. You will be able to mentally eliminate answer choices in a matter of seconds, leaving you with enough time to choose between two or three possible right answer choices per question. Good luck to you both!
