What is Weightage Percentage for a question?

Weightage% is by default calculated by LMS and updated based on the difficulty level of the question. The weightage% for the difficulty levels of questions are as follows:

1. Easy - difficulty level (auto-generated)
2. Medium - difficulty level doubles
3. Hard - difficulty level triples

For instance, the weightage% for three selected questions, with the below difficulty levels are as follows:

1. Easy - 10% 
2. Medium - 20% (10 * 2)
3. Hard -  30% (10 * 3)

Irrespective of the number of questions you select, LMS always equalizes the overall weightage% of questions for an exercise to 100%.
