I have encountered a grading issue with the **Problem Bank (Beta)** component that I am unable to resolve.

I created a Content Library and connected it to a Problem Bank in my course. I configured the bank to **randomly select 3 problems**. The randomization works perfectly; however, there is a major issue with the grade calculation.

I have set the subsection containing these questions as a ‘Final Exam’ and assigned it a weight of 100 in the grading settings. The progress and final grade are being calculated based on the **total number of problems available in the bank** , rather than the number of questions actually shown to the student.

In my case, I have 8 questions in the library but only display 3. Even if a student answers all 3 correctly, the final score is recorded as **37.5% (3/8)** instead of **100% (3/3)**.

When using the **‘Legacy’ Library Content** block with the same settings, the grade is correctly calculated based on the number of selected questions (3).

Is there any way to configure the **‘Beta’ Problem Bank** so that it returns a percentage based only on the number of questions randomly selected for the student?

Hi @TomaszCh - do you have any idea what version of the Open edX software your site is running?
