Questionaddition having null values in between Pin

I am designing a database for students management. For flexibility reasons I have kept it on a monthly basis wherein the students are awarded the number of lectures they have attended and zero if not. the department doesn't follow a strict time table hence there are times when there is no lecture for that subject during the entire day. The default value is null for such scenario. In short for each subject a student gets as following:
If present - number of lectures attended
if absent - zero
if no lectures for the day - NULL.
The problem is when adding up the entire column(yes column) if there is a null value the final answer is null. I want the answer to be summation of all the numbers present and Not count in the NULL values.
