⁠Features

⁠Starting an Exam

• Enter a topic name to identify the exam
• Optionally set Total Questions — if provided, a progress bar is shown during the exam and the exam auto-ends when the last question is answered
• Press Start or hit Enter to begin

⁠During an Exam

Answer options

• Select your answer letter by clicking (A–E by default)
• Answer selection is optional — you can skip recording a letter
• Add or remove options using the + / − buttons (supports 2–10 options, A–J)
• Click a selected letter again to deselect it

Recording the result

• Press ✓ Correct or ✗ Wrong to log the result — this immediately submits the question and advances to the next one, no extra button needed
• Keyboard shortcuts:
  • Enter or Space → Correct
  • W → Wrong

Timers

• Each question has its own timer that freezes automatically when you select Correct or Wrong
• A total exam timer runs continuously in the top bar
• The Pause / Resume toggle freezes both timers (useful for mid-exam breaks)
• Total exam time is calculated as the sum of per-question times, so idle time between finishing and ending the exam is never counted

Progress bar

• Shown only when a total question count was set at the start
• Displays answered / total and a percentage fill bar
• Automatically ends the exam when 100% is reached

Controls

• End Exam — manually end at any point
• The exam auto-ends when all planned questions are answered

⁠Results Screen

• Animated score ring with percentage
• Grade label (Excellent / Good Effort / Keep Practicing)
• Stats: correct count, total questions, total time, average time per question
• Full per-question breakdown showing answer letter, correct/wrong, and time taken

⁠History Tab

• Lists all past exams with score, date, question count, and total time
• Delete any exam (all question records are removed with it)

⁠Database

SQLite file location:

• Local: ./mcq.db (auto-created on first run)
• Docker: /app/data/mcq.db (inside the mcq-data volume)
