The marks your student receives on a custom task are calculated as follows:**Before the expiry date**

The number of ** sub**parts

**by the student is calculated. Each subpart is given equal weighting in their grade. Penalties are then applied depending on the subpart type:**

*attempted*- Multiple choice: An incorrect response
*or*a next step receives a 100% penalty. - A
*single step*subpart (no intermediate steps revealed, including graphing): Each incorrect response receives a 25% penalty (so two incorrect steps means 50%), and a next step receives a 100% penalty. - A
*multiple step*subpart (intermediate steps revealed): Each incorrect response receives a 25% penalty, and a next step receives a 50% penalty.

The penalties are applied and the result rounded to the nearest integer.**After the expiry date**

All subparts that have not been completed receive a 100% penalty, and their Grade is updated.**Worked example**

A task has 4 problems:

1. a. MCQ

b. Multi-step

2. Single-step

3. a. Single-step

b. Multi-step

c. Multi-step

d. Multi-step

4. Single step

A student produces the following:

1. a. No errors

b. Three incorrect steps

2. One next step

3. a. Two incorrect steps

b. One incorrect step, one next step

c. No response

d. No errors

4. One incorrect step

Before the expiry date, they receive the following penalties:

1. a. 0%

b. 75%

2. 100%

3. a. 50%

b. 75%

c. Not counted

d. 0%

4. 25%

The student receives a mark of

1/7 x ( 1 + 0.25 + 0 + 0.5 + 0.25 + 1 + 0.75 ) x 100% = 54%

After the expiry date, 3. c. is counted as zero, and they receive a 100% penalty for it. Their mark becomes

1/**8** x ( 1 + 0.25 + 0 + 0.5 + 0.25 + **0** + 1 + 0.5 ) x 100% = 47%

#### For Pearson users:

When calculating the total mark for homework, we weight each question equally at 1 mark each, regardless of how many subparts each question has.
