How To Increase Your Pediatrics Certification Exam By 50 Points

We already know pass rates for the ABP exam hover around 85% for all test-takers. This article is going to show two very easy ways to help increase your Pediatrics Certification score by 50 points. While there is no magic pill or wand to achieve this, these two techniques are the most useful, easy to implement and only requires a little of your time. This means anyone can take advantage of them. The first tactic is to use a system over a couple of months to identify what you don’t know. Sounds easy, right? The key is to go through a curriculum and identify what you don’t know – not what you are weak at – but what you don’t know. The second strategy is to take advantage of human error. Tests are written by humans, of course, and humans make errors. This article will show you 5 very easy techniques to narrow down an answer choice to either the correct answer or to a 50/50 probability – even without knowing anything about the topic. By combining these two strategies, you’ll be able to increase your Pediatrics certification score by 50 points – which could be the difference between passing or failing. Let’s get started.

Unknown unknowns

As you begin to study for your exam there are areas you know well and are comfortable with. Maybe you have a special interest in nephrology and feel confident with any question that might be asked on Fanconi syndrome. Because you are confident in nephrology you spend less time reviewing it. Let’s call this your known knowns. There is very little utility in spending too much time on your known knowns in preparing for your exam.

During medical training, I realized my understanding of liver disease was poor. Hepatic encephalopathy was just a term to me. I did not understand how or why it occurred and I had a poor grasp on managing the condition. Liver disease was a known unknown. Because I recognized this specific deficiency, I was able to target my learning to diseases of the liver. 

Once I started to focus my learning I came across many concepts and ideas that I knew nothing about…never even heard about some of them. These were the unknown unknown, a concept created by psychologists Joseph Luft and Harrington Ingham. It is part of their “Johari window,” a tool that helps users identify blind spots about themselves and others.

Known unknowns are things you’re aware that you don’t know—you can recognize that you don’t understand them. Unknown unknowns, however, are unexpected because you don’t know they exist.

The way to supercharge your In-training or Certification exam score is to identify your unknown unknowns. It takes a little effort, but it is rather easy. All you need are two things:

Notebook and time

The system works like this.

Step 1: You answer a question from a question bank. If you get the answer wrong, read the explanation. Then write down in your notebook the part of the explanation that describes why the correct answer is correct. This process helps to identify your unknown unknowns. Subsequently, if there is any other information that you did not know or somewhat knew, record it as well in your notebook under the same topic.

You must do this for every question you get incorrect. I also encourage it for questions you may answer correctly but discovered new information in the explanation that you previously did not know. 

Step 2: Start each study session by reviewing your notebook which contains the key knowledge that was previously unknown or weakly known by you. As you do more questions you are going to get questions wrong on topics already recorded in your notebook. For example, if you answer a question incorrectly on which age group most commonly gets de Quervain tendinopathy you’ll record in your notebook something like de Quervain tendinopathy: Epidemiology includes women between 30-50 yrs old and postpartum. Two weeks later you can’t name the diagnostic test characterized by thumb flexion and ulnar deviation of the wrist, you should go back through your notebook to find your first entry on de Quervain tendinopathy and add the Finkelstein test as the way to diagnose the condition. While we are on the topic, here is a cheat sheet for de Quervain tendinopathy.

After a month or two of recording your incorrect answer explanations, you will have a filled notebook of your unknown unknowns and maybe many of your known unknowns. If you do this on a consistent basis and get through 1,000 to 2,000 question bank questions for a 300-question standardized exam, you’ll have identified most of your blind spots that questions can be asked about. You end up converting your unknown unknowns to known knowns

Here is a page taken out of my notebook from 2004!


This is a Mead Composition notebook. All 100 pages (front and back) are filled with explanations from question bank questions I answered incorrectly.  

I use the same system and process to prepare for all standardized exams. And even used it to learn how to read EKGs better than a cardiologist.

Study schedule

By the end of residency, after taking four In-Training exams, my bookshelf looked like this


With the Pediatrics Certification exam around the corner, now is the perfect time to begin this system. It leaves time for adjustment and plenty of time to accumulate your unknown unknowns. Earlier in this post, I mentioned that to supercharge your standardized exam score you’ll need two things: a notebook and time. The notebook you can buy anytime. However, time disappears.

Identifying your unknown unknowns is how you can prepare to the lead up to your exams. But what can you do to improve your score simply by showing up to your exam?

How can you use the errors made by question writers to boost your score? 

The Anatomy of a Question

First, let’s understand the anatomy of a question.

A question is made up of the stem and the lead in. The stem is where you find all the details of the question such as the clinical presentation, past medical history, and laboratory results.  But, the critical part of the question is looking closely at the lead in. The question writer uses the lead in find out what you know or don’t know about the topic in the stem. But it is also the place where question writers make errors. By applying basic grammatical analysis, you will be able to identify the correct answer or at least narrow down the answer choices without knowing anything about the topic.

Here is an example of using grammatical cues.

Here is another technique that focuses on logical cues.

Let’s now focus on answer choices to identify a few more areas we can gain an edge.

The Anatomy of Answer Choices

Once you understand the goal of the question writer to create answer choices that are supposed to discriminate knowledge, it is easier to exploit technical flaws and improve the odds of getting a question correct.

Absolute terms
Long correct answer
Word repeats

Whether you are taking your In-Training exam or Certification exam, there is so much at stake. Taking the time to identify your unknown unknowns will not only help you prepare for and excel on your exam, you’ll expand your core knowledge. Then, on test day, use the simple techniques to identify common flaws in questions which will increase your chances of getting a question correct.

Give these methods a try and let me know how it goes. Moreover, I’d love to hear about techniques you use that I did not write about.

And if you are looking for a Pediatrics Board Exam Qbank…you know where to find one.

    Hi Adam,

    Thank you so much for this.

    I’m organizing myself to prepare for the Pediatric Boards this coming October – would you happen to know of/recommend a good Peds. Boards review audio/podcast?

    Thanks in advance.

      Dear Setarah,
      We are in the process of creating one and should be ready to help you for your October exam.
      Otherwise, I am not aware of any. Pediatric board review may have some resources for you.
