Hướng dẫn tạo đề trắc nghiệm với LaTeX

Summary

Project setup & compilation

• To use the project for testing, unzip it first.
• The main file has the same name as the output PDF.
  • The output “test demo” PDF derives its data from both:
    • the parent file, and
    • the main file.
• Renaming the main text file changes the generated PDF filename accordingly.
  • The PDF name reflects the main file name.

How the question banks are organized (LaTeX structure)

• Each chapter has its own question bank sub-file, for example:
  • Chapter 12
  • Chapter 3.4.4a
  • and also Chapter 1, Chapter 2, etc.
• Example workflow:
  • For Chapter 1, enter questions in the Chapter 1 file
    • (example question shown: “What fruit did Cinderella come out of?”).
  • To create multiple questions (e.g., 3 questions):
    • copy and paste the template question block, then edit it.
• Questions support math formatting using $...$ for formulas.
  • Example limit question behavior:
    • Incorrect answer examples: 1, ∞, -∞
    • Correct answer: 0
  • The LaTeX snippet likely distinguishes correct/incorrect answers via the provided answer labels.

Merging chapter question banks into a test (main/demo file)

• After building the question bank for each chapter, open the main/demo file to merge selected questions.
• In the test demo file (e.g., demo.tech), there are parameters, including:
  • Question count per test
    • e.g., change question number from 3 to 5 to alter how many questions appear.
  • School/organization name substitution
    • e.g., replace “Hanoi Pedagogical University” with another label such as:
      • “specialized high school for pedagogy”
      • “department”
      • etc.

Controlling which tests run (test code mapping)

• The test code’s first digit determines which set of tests to generate.
  • Example: if the base code is 100, subsequent tests become 101, 102.
• Rule for selecting question numbers by chapter:
  • e.g., take 2 questions from Chapter 1, 1 from Chapter 2, 1 from Chapter 3
  • by editing the chapter-wise numbers in the configuration.

---

Editing question types / environments

• If the test should not include essay-type questions:
  • Remove/delete the essay environment.
  • Update related symbols/sections (the subtitles mention adding a percent sign % to comment out or modify a section).

---

Common pitfalls mentioned

• Changes may not apply if you upload/edit the wrong file:
  • you must run the main file, not the “best file” (subtitle wording unclear).
• An error can occur when the same label appears twice.
  • Example mentioned: “B09” repeated leading to an error.
• Troubleshooting note:
  • A suspected incorrect percentage edit for Question 1 was checked, and it turned out:
    • Question 1 and Question 2 are fine
    • the issue is elsewhere.

Credit / closing note

• The video concludes that the process was created for the question bank and that questions are shuffled in the test package by Mr. Nguyen Huu Dien.

Main speakers / sources

• Mr. Nguyen Huu Dien
  • Credited for the question bank/test package and shuffling mechanism.
• Video narrator/instructor
  • Unidentified by name in the subtitles.
