How to Prepare for the Pre-hospital Trauma Life Support (PHTLS)

Based on analysis of thousands of successful candidates, we recommend a 12-week preparation plan with gradually increasing study intensity.
Recommended Study Timeline
Weekly study hours over a 12-week preparation period
Review Explanations Thoroughly
After each practice question, read the full explanation — even for questions you answered correctly. Understanding why wrong answers are wrong is as valuable as knowing the right answer.
Use Active Recall & Spaced Repetition
Research shows active recall combined with spaced repetition (FSRS algorithm) produces 2-3x better long-term retention than passive reading or highlighting.
Create a Structured Study Plan
Break your preparation into weekly milestones. Allocate more time to high-weight topics and schedule regular review sessions to reinforce earlier material.
Focus on High-Yield Topics First
Identify the exam content domains that carry the highest weight and master those first. This ensures maximum point potential even if time runs short.
Practice with Timed Mock Exams
Simulate real exam conditions by taking full-length timed practice tests. This builds stamina, reduces test anxiety, and identifies weak areas under pressure.
Take Care of Your Health
Sleep deprivation decreases cognitive performance by up to 40%. Maintain regular sleep, exercise, and nutrition during your study period for optimal brain function.
Common Mistakes to Avoid
Many candidates make preventable mistakes during their Pre-hospital Trauma Life Support (PHTLS) preparation. Being aware of these common pitfalls can save you weeks of ineffective studying and significantly increase your chances of passing on the first attempt.
Starting preparation too late
Begin at least 8-12 weeks before your exam date to allow adequate time for all content domains and multiple full-length practice tests.
Ignoring the exam format and timing
Practice under realistic conditions. Know exactly how many questions, how much time per section, and what question types to expect.
Cramming the night before
The night before the exam, do a light review and get a full night of sleep. Last-minute cramming increases anxiety and impairs recall.
Passive reading without self-testing
Replace re-reading with active recall: close the book and try to explain concepts from memory, then check your accuracy.
Neglecting test-taking strategies
Learn to eliminate obviously wrong answers, manage your time per question, and flag difficult items to return to later rather than getting stuck.
Spending too much time on easy topics
Focus your energy on weak areas and high-weight domains. Track your performance by topic to identify where extra study time will have the most impact.
