Every regular creiit (non extra credit) assignment is graded and given a number of points. In the end all points are summed up ; this is P quantity in grade formula below. The sum of maximum number of points on regular credit is the quantity T in grade formula. Note that if T=P , even with no extra credit, you obtain the maximum grade.
Make sure you understand how extra credit points contribute to your grade !
EXTRA CREDIT PROVIDE A LOWER BENEFIT THAN REGULAR CREDIT, so only work on EC after you finished the RC.
EXTRA CREDIT POLICY. There will be several projects/problems that students can work on for extra credit. They are clearly specified on assignments. For each one of those :
If at least half of the points are obtained, score is going to be doubled.That is, if a extra-credit problem is worthed 75 points and you get by normal grading 40 points, it will count as 80 extra credit points.
if less than half of the points are obtained, the problem will be scored 0 (zero) extra credit points.
The sum of extra credit points is quantity E in grade formula below.
grade = (P+E) / (T+E)This formula may apply for exam grade (with exam EC) and separately for HW (with HW EC). Usually we will not combine EC obtained on HW with the exam grade.
