Math Test-takings Tips
- Master the Fundamentals: Build a strong foundation in core math concepts like basic operations, fractions, decimals, percentages, and simple equations. A shaky foundation will make harder problems much more difficult.
- Read Carefully, Decipher the Question: Take the time to understand exactly what the problem is asking. Identify keywords and what information is important. Misinterpretation can lead to incorrect solutions.
- Simplify and Break it Down: Complex problems can be overwhelming. Break them into smaller, more manageable steps. Focus on the core elements and eliminate distractions.
- Practice at a Higher Level: Challenge yourself with slightly more difficult practice problems than you expect on the test. This builds confidence and makes test-day questions feel easier.
- Work Backward for Insight: If you’re stuck, try plugging in answer choices into the problem. This can sometimes lead you to the solution or eliminate incorrect options.
- Manage Your Time: Be aware of how much time you’re spending on each question. Don’t get bogged down by a single problem. If needed, skip it and come back later with fresh eyes.
- Check Your Work Meticulously: Even if you’re confident, take a few moments to double-check your calculations and ensure your answer makes logical sense within the context of the problem.

IBEW Reading Comprehension Practice Questions
Sample Question #15
For decades, the construction industry has relied on traditional materials like concrete, steel, and lumber. These staples are readily available and their properties are well understood by architects and engineers. Recently, there has been growing interest in sustainable building practices, promoting the use of ‘green’ materials that have less environmental impact. Examples of these alternative materials include bamboo, recycled plastic composites, and even compressed straw bales. However, the widespread adoption of these materials faces barriers. Costs can be higher than traditional options, and many building codes were written without them in mind. This means builders might require special permits or variances, increasing project complexity.
Question:
Based on the information in the passage, which of the following challenges to sustainable building practices is most strongly implied?
A. Lack of skilled labor with experience in green materials.
B. Public distrust of the safety and durability of new materials.
C. Limited availability of alternative building materials.
D. Regulatory hurdles in the construction process.
Sample Question #16
Elephants are social creatures, relying on complex communication within their herds. This communication encompasses a wide range of sounds, including low-frequency rumbles, trumpets, and roars. However, human activities are disrupting these crucial communication channels for elephants. Noise pollution from traffic, machinery, and low-flying aircraft can mask or interfere with their calls. Additionally, habitat fragmentation can scatter herds and increase the distances over which they need to communicate. These disruptions have been linked to stress within herds and may compromise their ability to find mates or food sources.
Question:
The passage suggests that human activities impact elephants primarily by:
A. Causing direct harm to their hearing.
B. Disrupting their social structures and behaviors.
C. Altering food availability in their habitats.
D. Increasing the risk of poaching and illegal trade.
Sample Question #17
The era of the American Civil War (1861-1865) saw significant advancements in military technology. Innovations like the repeating rifle and ironclad warships transformed the battlefield. However, medical practices lagged considerably behind these technological leaps. Battlefield surgeons lacked effective sterilization techniques and an understanding of germ theory. As a result, infections were rampant, and amputation was often the only way to treat severe injuries. These conditions led to a staggering number of casualties and made battlefield medicine one of the war’s deadliest aspects.
Question:
Which of the following titles best summarizes the main idea of the passage?
A. Medicine and Technology During the Civil War
B. The Importance of Amputation Techniques
C. The High Casualty Rate of the Civil War
D. The Rise of Ironclad Warships

Reading Comprehension Test-taking Tips
- Target the Task: Begin by carefully reading the questions. This helps you focus your reading and identify what information you need to extract from the passage.
- Scan for Structure: Quickly skim the passage to get a sense of its overall organization. Note any headings, topic sentences, or key transitions. This gives you a framework for understanding the text.
- Mark Key Points: While reading actively, underline or highlight important ideas, keywords, or phrases that seem confusing. Pay additional attention to how those ideas relate to the test questions.
- Refer Back Strategically: Now revisit the questions. Try to answer them based on your understanding and the highlighted parts. Use the passage itself as your primary source of evidence.
- Targeted Rereading: If you’re stuck, don’t reread the entire passage aimlessly. Focus on the sections containing your highlighted portions, searching for clues that connect to the question.
Many consider the reading comprehension portion the easier part of the exam. That being said, you shouldn’t neglect it as it makes up 50% of your score. Check our detailed guide to see what question types are the most difficult on this test.
Understanding Your Test Scores
The IBEW aptitude test is more than just a pass or fail test.
Your score on the test is extremely important, as it is the only factor determining your interview eligibility.
The passing score is usually getting into the 4/9 of test-takers. Still, in highly competitive locals or unions, where more people tend to apply, this boundary might be harder to reach than others.
Additionally, If you only reach the minimum passing score, you may be pushed down the line by applicants who scored higher. That’s because recruiters invite applicants for an interview starting from the top of the list to the bottom.
