LET Reviewer: 5 Practice Questions
Science • Communication • Mathematics • Law & General Education
Preparing for the Licensure Examination for Teachers (LET) requires more than memorizing answers. You need to understand the concept behind each question so you can apply the same principle when the wording or choices change.
In this LET reviewer, we will examine five practice questions covering energy transformation, nonverbal communication, metric conversion, just compensation, and fractions. Each item includes a detailed rationale, common mistakes, exam strategies, and a quick-review section.
📚 Table of Contents
Question 1: Energy Transformation
When lighted, the energy of the alcohol in a lamp is:
- Transformed from chemical energy
- Transformed from chemical to heat energy ✅
- Lost while heating is done
- Completely destroyed
Detailed Rationale
Alcohol contains stored chemical energy. When the alcohol is burned, a chemical reaction called combustion occurs. During combustion, the chemical energy stored in the alcohol is converted primarily into thermal energy (heat) and also into light energy.
Therefore, the best answer among the choices is that the energy is transformed from chemical energy into heat energy.
Energy is not destroyed during the process. Instead, it changes from one form to another. This illustrates the principle of the Law of Conservation of Energy.
Concept to Remember
Chemical energy → Thermal energy + Light energy
Priority Learning Point
When a question describes burning fuel, food, wood, gasoline, candle wax, or alcohol, identify the original form of energy and determine what form it becomes after the process.
Safety Considerations
Alcohol is highly flammable. In real-life laboratory or classroom situations, alcohol lamps should be handled only according to appropriate laboratory safety procedures.
Clinical / Teaching Pearl
For teaching purposes, connect energy transformation to everyday examples: food provides chemical energy, electrical appliances convert electrical energy into other forms, and burning fuels converts chemical energy into heat and light.
Common Mistakes
- Thinking that energy disappears after combustion.
- Choosing “completely destroyed.”
- Ignoring the word transformed.
- Memorizing the answer without understanding conservation of energy.
LET Tip
Whenever the question involves energy, ask: “What form of energy was present before the process, and what form is produced afterward?”
Quick Review
Question 2: Body Language and Communication
Pre-school children always watch the body language of their teachers. This means ____.
- Communication is best by movement and gestures ✅
- Communication is best by words
- Communication is best by the tone of voice
- Communication is best by group discussions
Detailed Rationale
Body language is a form of nonverbal communication. It includes gestures, posture, facial expressions, eye contact, body movements, and other physical behaviors that communicate meaning.
Young children often observe the behavior and body language of adults to determine whether a person is friendly, angry, encouraging, concerned, or uncomfortable.
Therefore, among the choices provided, movement and gestures best represent the concept being tested.
Assessment
A teacher should assess not only what children say but also how they respond through facial expressions, gestures, posture, eye contact, and behavior.
Teaching Intervention
Teachers should use clear, consistent, and age-appropriate verbal and nonverbal communication. A supportive facial expression, appropriate eye contact, and calm gestures can reinforce positive classroom interactions.
Evaluation
Effective communication can be evaluated by observing whether learners understand instructions, respond appropriately, participate, and demonstrate the intended behavior or learning outcome.
Safety Considerations
Teachers should avoid threatening gestures, aggressive posture, humiliating expressions, or intimidating physical behavior, especially when communicating with young children.
Clinical / Teaching Pearl
What you do can communicate as strongly as what you say. A teacher who tells learners to remain calm while displaying an angry facial expression may send a conflicting message.
Common Mistakes
- Assuming communication only means spoken words.
- Confusing body language with tone of voice.
- Forgetting that gestures and posture are forms of nonverbal communication.
- Choosing the most complicated-sounding option instead of identifying the tested concept.
LET Tip
If a question mentions gestures, facial expressions, posture, eye contact, or body movements, think: NONVERBAL COMMUNICATION.
Quick Review
Question 3: Metric Conversion
If you were converting the height of your room for better ventilation, what would 1.60 m be equivalent to?
- 16 cm
- 1,600 mm ✅
- 1,600 cm
- 1.6 dm
Detailed Rationale
The metric system is based on powers of 10. To convert meters to millimeters, multiply by 1,000.
1 meter = 1,000 millimeters
Therefore:
1.60 m × 1,000 = 1,600 mm
Therefore, 1.60 meters is equivalent to 1,600 millimeters.
Assessment
The key skill being assessed is the learner's ability to convert between metric units accurately.
Planning / Problem-Solving Strategy
Before calculating, identify the starting unit and the target unit. Here, the starting unit is meters and the target unit is millimeters.
Intervention / Solution
Use the conversion relationship: 1 m = 1,000 mm. Move the decimal point three places to the right when converting meters to millimeters.
Evaluation
Check whether the result makes sense. Since millimeters are much smaller units than meters, the numerical value should become larger.
Common Mistakes
- Writing 1.60 m as 160 cm without checking the conversion.
- Confusing millimeters with centimeters.
- Moving the decimal in the wrong direction.
- Thinking that changing units changes the actual physical measurement.
LET Tip
Remember the basic metric relationship:
When moving toward a smaller unit, the numerical value becomes larger.
Quick Review
- 1 m = 100 cm
- 1 m = 1,000 mm
- 1 cm = 10 mm
Question 4: Just Compensation
It refers to the full and fair equivalent of the property taken from its owner by the expropriator, and the gauge for computation is not the taker's gain but the owner's loss. In order for the payment to be “just,” it must be real, substantial, full, and ample; made within a reasonable time from the taking of the property.
- Property
- Public use
- Eminent domain
- Just compensation ✅
Detailed Rationale
Just compensation refers to the fair payment due to a property owner when private property is taken for a public purpose through the exercise of the government's power of eminent domain, subject to constitutional and legal requirements.
The important distinction in this question is that eminent domain is the government's power to take private property for public use upon payment of just compensation, while just compensation refers to the compensation or payment made to the owner.
Since the question specifically asks for the full and fair equivalent of the property taken, the correct answer is just compensation.
Key Legal Distinction
Eminent Domain → The power to take private property for public use, subject to legal requirements.
Just Compensation → The fair compensation paid to the property owner for the property taken.
Assessment
The question assesses the examinee's ability to distinguish related legal concepts rather than merely recognize individual definitions.
Priority Learning Point
Focus on the wording of the question. If it describes the payment or fair equivalent received by the property owner, think just compensation.
Safety / Professional Considerations
Legal questions in board examinations should be answered based on the applicable law and the exact wording of the question. Avoid applying a general rule when a specific legal provision controls.
Common Mistakes
- Choosing eminent domain because the question mentions taking property.
- Confusing the government's power with the compensation paid to the owner.
- Ignoring the phrase “full and fair equivalent”.
LET Tip
When choices contain both eminent domain and just compensation, look for what the question is actually asking:
Fair payment for property taken? → Just Compensation
Quick Review
Just compensation is the compensation owed to the property owner when private property is taken for public use under the exercise of eminent domain.
Question 5: Equivalent Fractions
Which of the given fractions is equal to 12/84?
- 7/42
- 1/8
- 6/42
- 1/7 ✅
Detailed Rationale
To simplify a fraction, divide both the numerator and denominator by their greatest common factor.
For 12/84, both numbers can be divided by 12:
12 ÷ 12 = 1
84 ÷ 12 = 7
12/84 = 1/7
Therefore, 1/7 is the equivalent fraction in simplest form.
Assessment
This item assesses basic mathematical reasoning, particularly the ability to simplify fractions and recognize equivalent values.
Problem-Solving Strategy
- Identify a number that divides both numerator and denominator.
- Divide the numerator by that number.
- Divide the denominator by the same number.
- Check whether the resulting fraction is in simplest form.
Evaluation
Multiply the simplified fraction by the number used to reduce the original fraction:
1 × 12 = 12
7 × 12 = 84
Therefore, 1/7 is equivalent to 12/84.
Common Mistakes
- Dividing the numerator and denominator by different numbers.
- Stopping before reaching the simplest form.
- Comparing only the numerator or denominator.
- Doing mental calculations too quickly without checking the result.
LET Tip
For equivalent fractions, always remember:
Quick Review
12/84 → divide both by 12 → 1/7.

🎯 LET Study Tips
These five questions demonstrate an important LET reality: questions may jump from science to communication, mathematics, law, or other general education concepts.
- Understand concepts instead of memorizing answers. The same concept can appear in a completely different situation.
- Watch for keywords. Words such as “transformed,” “body language,” “equivalent,” and “fair payment” provide clues.
- Eliminate clearly incorrect choices. This is especially useful when two choices initially appear possible.
- Check mathematical answers. Don't rely solely on mental computation when a quick calculation can prevent an avoidable mistake.
- Study related concepts. After answering a question about eminent domain, for example, review just compensation and related legal terminology.
- Practice under time pressure. The goal is not only to know the answer but also to recognize the concept quickly.
