When pocket calculators can store… "the whole world"
Many students like NNL (grade 9 in Ho Chi Minh City) accidentally came across and were attracted by the video "How to cheat on Casio calculators that teachers don't want to show you" on YouTube. Specifically, the method mentioned by the channel owner is to enter a command to display a 4-column matrix frame like the 4 multiple choice answers A, B, C, D, then enter the answer known in advance thanks to extra classes or asking questions from other classes into the frame and save it on the computer until the test is done. "So you have successfully cheated," this person concluded the video.
The video was posted on September 21, receiving a "huge" number of interactions of more than 1.9 million views and hundreds of mixed comments. Under the post, in addition to comments expressing interest in the cheating method, there were also critical opinions. NHQ account was indignant: "Don't do it because this action will destroy logical thinking, instead, circle the answer without knowing what the question asked...". BLGC account said that this method is not "easy to eat", it is just that the content creator is "hungry for views".
Video on September 21 about cheating with a calculator
This is not the only video about saving answers in a calculator, there are even ways to do it for different types of computers or "tricks" to save subject knowledge in numerical form such as the number of sides of a polygon, historical timeline... However, this trick is easier to "fool" teachers when applied to natural subjects that require using a calculator while doing the test.
Many risks
Some students like Vu Phuong Linh (grade 11, Pham Hong Thai High School, Hanoi) said that they did not know about the tricks shared on social networks but realized the risks they could face if they applied them. "Teachers only need to change the questions and students will be confused," Linh said.
The reason why cheating can be solved by simply changing the test questions is because some teachers often use the same set of questions for their classes, so the class that takes the test first will inform the class that takes the test later to "prepare", according to MT (a student majoring in business administration, Saigon University). In addition to depending on the questions, T. believes that if the teacher/supervisor requires the calculator to be reset before the test, students cannot cheat.
On the teacher's side, Mr. Nhat Tuan, who teaches high school math in District 6, Ho Chi Minh City, noted: "The matrix function of a pocket calculator only contains a limited number of cells, so it cannot store too much data. Students with exam-related psychology cannot remember the answers to each question to circle multiple-choice questions smoothly."
From here, Mr. Dinh Xuan Nhan, a math teacher at Tran Khai Nguyen High School (District 5, Ho Chi Minh City), commented that the videos on YouTube mainly "attract views" from "gullible" students because this trick only happens with small, internal tests and the test takers are dishonest, and are not useful in large exams with high security.
Therefore, Mr. Xuan Nhan advised students to be alert to risks and not to follow tricks. In the long run, teachers agreed that the biggest risk is the direct impact on students' thinking and learning attitude.

Why the trick?
When she was in high school, TMH (a student at the University of Social Sciences and Humanities, Ho Chi Minh City) also used the storage feature as in the video above to reduce the burden of memorizing about 30 figures of a mathematical polygon. "I tried to memorize them, but every time I encountered a problem, I felt confused, so I had to use a trick," H. said. Similarly, MT (a student at Saigon University) thought that no one could learn all the polygon figures when this content only had 1 question on the exam.
According to Mr. Xuan Nhan, the functions of a pocket calculator are all intended to support calculations, so the fact that some features are "deformed" is not the fault of the calculator but of the user.
Meanwhile, teacher Nhat Tuan believes that tools with many features always come with "loopholes" for students to take advantage of and become dependent on calculators without thinking about problem solving.
Some teachers assert that it is unforgivable to cheat on calculators in exams. According to the regulations on high school graduation exams issued by the Ministry of Education and Training, candidates are prohibited from bringing into the exam room any device containing information that could be used to cheat during the exam; candidates are only allowed to bring calculators according to regulations, without text editing functions or memory cards for storing data. If a candidate violates the regulations, they will be ticketed, have their evidence confiscated, and be suspended from the exam.
To avoid cheating that can lead to unpredictable consequences, Mr. Xuan Nhan suggests that students take the following steps if they want to memorize effectively during the learning process:
- Identify key knowledge clusters and main ideas of each cluster
- Ask yourself questions to proactively grasp knowledge
- Distinguish similarities and differences between knowledge
- Systematize with mind maps and solve problems regularly
As for teachers, he emphasized the importance of designing and securing test questions if they have grasped the above trick, in which the questions should use new data, avoiding duplication with available documents.
