Practice questions are the best way to test your understanding and retention of the material you have covered. They allow you to identify your strengths and weaknesses and prepare you for the type of questions you will see on the USMLE Step 1 Exam.
Complete a Realistic Amount of Questions
Set a realistic amount of practice questions that you would like to complete every day. Usually around 100 questions a day during a 12-hour study day is appropriate. Such a day may be organized as follows: 8am-12pm Read/Review Subject #1, 12pm-1pm Break, 1pm-5pm Read/Review Subject #2, 5pm-6pm Break, 6pm-10pm Practice/Analyze questions from Subject #1 and Subject #2.
Practice under timed conditions. The question stems for USMLE Step 1 tend to be lengthy and you will often be skimming through information rather than methodically reading every line.
Review the explanations for questions you answered incorrectly as well as correctly. You will learn a tremendous amount by going over every question. This is important even for the questions you answered correctly as you may not have utilized the same thought process to arrive at the answer.
Annotate your review book with lessons you learned from practice questions. Practice questions may often fill gaps that are not covered within the resource book that you use or encourage you to look over a high-yield topic once more.
Re-take questions you answered incorrectly. Repetition is essential for long-term retention and repeating questions you answered incorrectly would encourage you to avoid making the same mistakes.
