There are two training modes. training modes:

• ‘Random selection’
• ‘Lab after lab’

‘Lab after lab’ is probably the most effective training mode, since each value must be answered correctly before all values are asked again. This approach is commonly known as “spaced repetition”. It is based on the psychological principle that spacing out the review of information over time leads to better long-term retention compared to cramming or constant repetition. In the context of the fretboard quiz, here’s how it works:

1. Initial Learning: Users are presented with a set of values (e.g., fretboard positions or notes) to learn.
2. Testing: Users are quizzed on these values. If they answer a value correctly, it may not be presented again immediately.
3. Repetition: Values that are answered correctly are scheduled to be presented again at increasing intervals. This means that users will encounter them again, but the time between repetitions gradually increases.
4. Feedback Loop: Values that are answered incorrectly are presented more frequently until the user consistently answers them correctly.
