If you stick to your plan, reward yourself. Be honest about your habits. Design and personalize your plan. Divide the materials into bite-size chunks and study whenever you have a free moment. Communicate your goal to family, friends, and colleagues.
Communication is key.
If people understand the time commitment you must make, they often will assist you. Practice, practice, practice. The best way to learn is by doing. Practice questions and learn from your mistakes. Test your working knowledge of the material.
