** GRADES DATABASE**

**Regular credit.**

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.

**Extra credit.**

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 FORMULA.

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.**GRADES ASSIGNMENT (tentative plan - adjustments may apply to this scheme)**
