## Re-grading of questions

One of the most appreciated aspects of BuildUp is the adjustment of the questions difficulty to the level of the student. By analysing 4 years of data on student responses, we have been able to regrade each question to a much more precise level of difficulty. This makes the sequencing for each student more effective, reducing learner frustration and increasing learning effectiveness.

## Corrections based on feedback

Within each question, there is an option to "Help improve this question". As both students and teachers have provided feedback, we have completed the review and update of question errors based on this feedback.
