LET General Education Practice Test
5 Questions with Answers & Rationalization
Test your knowledge and strengthen your LET General Education preparation.
Preparing for the Licensure Examination for Teachers (LET)? Test your knowledge with these LET General Education practice questions with answers and rationalization.
This practice set covers important topics in Science, Electricity, Health Education, English Grammar, and Philippine Government. Try answering each question before checking the correct answer and explanation.
Don't simply memorize the answer. Understand the concept behind each question so you can apply the same principle when you encounter a differently worded question in the examination.
1. Science: Experimental Design
The class was asked to design an experiment to test the effect of detergent on fish. One group came up with this experimental design. For detergent they got Ariel, Surf and Tide. For fish they had tilapia, goldfish, and janitor fish contained in different sizes and shapes of bottles. To the tilapia they put 1 tbsp. of Ariel. To the goldfish, they put 1 tbsp. of Surf and to the janitor fish, 1 tbsp. of Tide.
How can the experimental design be improved?
I. Make use of the same type and size of fish
II. Increase the number of fish & reduce the number of detergent brands involved
III. Focus on one independent variable at a time, e.g. brand of detergent
A. I only
B. I and III
C. I and II
D. II only
Rationalization
The experiment has several variables that could affect the results. The researchers are using different types of fish and different containers while simultaneously testing different detergent brands. This makes it difficult to determine whether the observed effect is caused by the detergent or by another variable.
Statement I is correct because using the same type and size of fish helps control the characteristics of the test subjects.
Statement III is also correct because a well-designed experiment should control variables and clearly identify the independent variable being tested.
Statement II is not the best choice because simply increasing the number of fish while reducing detergent brands does not by itself address the need for proper control of variables.
2. Electricity: Direct Current
What do you call the charges in an electrical circuit flowing in the same direction?
A. Constant current
B. An alternating current
C. Direct current
D. Basic current
Rationalization
Direct current (DC) is electric current that flows predominantly in one direction. Batteries are common sources of direct current.
In contrast, alternating current (AC) periodically changes direction. Household electrical power is commonly supplied as alternating current.
🔋 DC – Direct Current → flows in one direction
⚡ AC – Alternating Current → periodically changes direction
3. Health Education: Preventing Intestinal Diseases
One good rule to avoid intestinal diseases is _____.
A. Wash your hands before eating
B. Wash your feet before going to bed
C. Sleep under a mosquito net
D. Avoid insect bites
Rationalization
Proper handwashing is one of the most important ways to help prevent the spread of many infectious diseases, including illnesses that can be transmitted through contaminated hands, food, and surfaces.
Washing hands before eating reduces the possibility of transferring disease-causing microorganisms from the hands to the mouth.
Sleeping under a mosquito net and avoiding insect bites are important preventive measures for certain vector-borne diseases, but they are not the primary measure described in this question for preventing intestinal diseases.
4. English Grammar: Sentence Correction
The respiratory membrane, through which exchange of gases occurs, are the things of the lungs.
A. Through which gas is exchange
B. After gasses are exchange
C. Through which exchange of gas occurs
D. No change
Rationalization
The supplied review material identifies D. No Change as the keyed answer.
The phrase “through which exchange of gases occurs” is grammatically structured as a relative clause and appropriately describes the function of the respiratory membrane.
However, the wording “are the things of the lungs” appears unusual and may reflect a transcription or source-text issue. In a standard English grammar exercise, the complete sentence would normally be expected to use medically and grammatically precise wording.
Therefore, students should treat this item as a source-based review question and verify the original wording when possible.
5. Philippine Government: Local Government
In the Philippine government, the earliest and smallest service of governance is the:
A. Municipality
B. Poblacion
C. Barangay
D. Barrio
Rationalization
The barangay is the basic political and governmental unit in the Philippines. It is the smallest local government unit and serves as the fundamental level of local governance.
A municipality consists of several barangays, while a poblacion generally refers to the central or administrative area of a municipality or city.
The term barrio is historically associated with the barangay but is not the current formal term for the country's basic political unit.

📖 How to Prepare for LET General Education
General Education covers a broad range of subjects. The best way to prepare is to combine concept review with regular practice questions.
- Review the basic concepts. Focus on the principles commonly tested in each subject.
- Practice different question types. Don't limit yourself to definition-based questions.
- Analyze your mistakes. Determine why your answer was incorrect.
- Create quick-review notes. Record formulas, definitions, principles, and important facts.
- Practice consistently. Short, regular practice sessions can help strengthen recall.
