There is an aspect of scoring well on standardized testing that is often overlooked: minimizing careless mistakes. Depending on the starting score, we observe that up to one-third of a student’s incorrect answers may stem from carelessness. While it’s easy to brush this off either as inevitable or as something that will fix itself with repetition, remember that the test does not care why you got a question wrong: all incorrect answers cost you the same number of points. Students should view careless errors with the same seriousness as they view content gaps. By identifying the root causes of carelessness, we can implement practices that will minimize careless mistakes and save valuable points.
Fixing any problem starts with understanding it. In standardized testing, there are two broad reasons we might get a question wrong: we don’t understand the underlying academic content, or we make a mistake. In the latter case, we often respond with, “I knew that! That was so silly!” Thinking that there isn’t anything to really be learned, we move on with a vague idea to “not do that anymore.” This lack of retrospection can lead to a rushed correction, more mistakes, and frustration. We call this the understanding delusion: in short, we are stuck in a cycle of error. The key to breaking this cycle is realizing that careless mistakes are gaps in knowledge. While a student may possess the academic knowledge to solve a problem, careless mistakes often reveal a lack of procedural knowledge. Only by adequately identifying and addressing the procedural knowledge gap can we prevent future careless mistakes.
One helpful way to frame mistakes is to view them as essential to the test prep process. We must make mistakes in order to diagnose and address our weaknesses. Instead of being frustrated or discouraged by mistakes, consider them as invaluable learning opportunities. Look carefully at the questions you miss and classify them as stemming from a lack of academic knowledge or from careless mistakes. Within the latter category, identify specifically how you were careless. (“I didn’t distribute to both terms”; “I didn’t identify the correct axis”; “I didn’t re-read the entire line reference.”) It will not take you long to notice patterns, even amongst the questions that you “know” how to do. Once you’ve identified these patterns, you’ll be able to recognize the question types where you are most likely to make careless errors and proceed with caution. In other words, you’ll be able to predict (and prevent) your careless mistakes.
To summarize, follow these simple steps to minimize carelessness and increase your score:
Write out every step of your work on all problems.
If you get a question wrong, cover your work and solve it again.
Identify your mistake.
Classify your mistake.
Find patterns.
Predict and prevent!
Happy testing!
