Set Correct Answer and Scoring
Step 1: Point Value and Correct Answer
Is there more than one correct answer?
Do you need to accept a range of answers (tolerance)?
Step 2: Scoring Method
Choose from the following scoring methods:
💡 Tip from the Otus Team: equivSymbolic is the most commonly used method, and will provide the most flexibility when scoring. See details below.
Only accepts a response that is mathematically equivalent to the correct answer AND is given in the same form.
Will accept a response that is mathematically equivalent to the correct answer, even if they are in different forms. This is the method you should use if your answer involves variables or if your answer involves multiple parts that can be in any order.
Very similar to equivSymbolic, but equivValue will compare numerical values thatmay be represented in different ways, such as units of measurement. It is most often not necessary to use equivValue (when in doubt, use equivSymbolic).
➡️ Allow Decimal Marks
In any one of the above cases, if the answer allows for comma separators, please check the Allow Decimal Marks option!

Step 3: Repeat for additional response boxes
Step 4: Scoring Type.
➡️ Exact Match
The entire question must be answered correctly to receive the point(s).
➡️ Partial Match per Response
Each response is scored independently, and each is worth the number of points indicated in the point(s) field.
➡️ Partial Match
Similar to partial match per response, each response is scored independently, but the point value indicated in the point(s) field is evenly split among the responses.
