We have a process for evaluating how candidates score at each task to be sure their difficulty level fits into the right category.
Each task we release we analyze further based on how candidates score at it. If we see that, for example, candidates fail too often on a task marked as easy we change its difficulty to medium.
Right now we're changing the difficulty level of 9 tasks:
This change affects mostly customers who are going to create new tests.
If you were using one of those tasks, that doesn't necessarily mean you need to change anything - signal you're getting is going to remain the same so in most cases, you don't need to adjust your current tests.
