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.
