Workaround:

1. Turn "Custom Scoring" Off
2. Set "Minimum number of questions" to the number of questions a student should answer

This way if a student ends the lesson prematurely, their correct answers is divided by the "Minimum number of questions" instead of the number of questions viewed.

Reason why this does not work for "Custom Scoring" On is because one cannot assume the point value of the questions that were never answered. With "Custom Scoring" Off, each question is essentially worth one point each, but with it On, any question can be worth any point value. So, dividing the points earned by "Minimum number of questions" would not make since because that would assume that all the questions have a max score of 1.

Only solution that comes to mind is to make "Required" questions. These "Required" questions should be answered and are always used in the calculation of the final grade. This would be a rather large change though :\

Another way to re-produce this is to answer the first question, then change the URL to mod/lesson/view.php?id=X&pageid=-9 where X is the course_module ID of the Lesson (easy to find). Sends you to the end of the lesson and grades it. Big problem if a student finds out and the teacher does not check their attempt in Lesson reports.

I think that when custom scoring is used, the points earned should be matched against the total points directly. So in the example situation, if the student answers 5 1 point questions on a 10 point lesson, they should get 5/10. If one of the questions they answer correctly is worth 5 points, they should get 9/10 (4x1 + 5)/10.

If the get kicked out of the lesson due to the timer being up after they have earned 5 points (by answering what ever range of questions correctly) they should get 5/10.

Since attempts (on a question) are currently assigned the last score (if attempts are =3 I can get full credit for the question on the last attempt), this should work for custom scoring fine: if a student has 3 pts when they are kicked out of a lesson due to the time being up, they should get 3/10 for a grade, not 10/10 as it currently (reproduced in 1.6 just now) sits.

Long run I think we should strive to comply with IMS QTI (perhaps Jeff and/or Gustav could help with the definition for "an integer with single cardinality." used by IMS?->

Only problem with Michael's proposed solution is that old lesson's could easily break. For example: a large lesson with 30 questions that has max grade set to 10. The student would only have to get 10 out of the 30 questions correct to get 100% if each question was worth 1 point.

Also, this is somewhat a burden on the creator because s/he would have to add up all the points in the lesson to set max grade to the appropriate number.
