Your approach is theoretically appealing, as it allows for flexibility and customization according to each student's level and readiness, which could significantly boost engagement and learning outcomes. However, in practice, implementing individualized tasks and grading each separately could become challenging, especially if there are numerous participants. Tracking and assessing personalized tasks might require more time and effort than anticipated, making it difficult to maintain consistency in feedback and scoring.

To find a middle ground, one solution could be to create a structured homework format with predefined tasks categorized by difficulty level. This way, users can select tasks based on their confidence and skill, while you maintain control over the assignment options, making grading more manageable.
