[Data science](https://help.hackerearth.com/assessments-recruiters?hsLang=en#data-science) # Partial scoring In a Data Science question, you can add multiple test cases with varying scores to evaluate a candidate’s submission. This is known as partial scoring.  Each test case can be assigned a score. You can follow the provided steps to add partial scoring in your data science question: 1\. Add a Data Science question to a test. *Note*: You can either select an existing data science question from the library or create a new question. 2\. Select the question and click **Edit question**. ![DS7.png](https://help.hackerearth.com/hubfs/Knowledge%20Base%20Import/DS7-1.png) 3\. Click **Data & test cases**. ![DS8.png](https://help.hackerearth.com/hubfs/Knowledge%20Base%20Import/DS8-1.png) 4\. In the **Checker** section, click **Add checker file** **![DS9.png](https://help.hackerearth.com/hubfs/Knowledge%20Base%20Import/DS9-1.png)** 5\. Upload the full expected output (**Expected output)** and the **Checker** file. Enter **Maximum score** for each test case and select the respective **Checker language**. Then, click **Upload**. ![DS10.png](https://help.hackerearth.com/hs-fs/hubfs/Knowledge%20Base%20Import/DS10-1.png?width=607&height=392&name=DS10-1.png) **6. Set as sample checker**: You can set a test case (Expected output and Checker) as the sample checker. Once you select a test case as the sample checker, it will be used as a sample Expected output. In other words, when you click **COMPILE & TEST**, the enabled test case will be used to evaluate the submission. The other test cases will be used to evaluate the submission when **SUBMIT** is clicked. ![DS11.png](https://help.hackerearth.com/hubfs/Knowledge%20Base%20Import/DS11-1.png) Example The following example has two test cases. Each test case has a unique evaluation metric to evaluate the submission.  ![DS12.png](https://help.hackerearth.com/hubfs/Knowledge%20Base%20Import/DS12-1.png) Here, *Checker 1* uses F1 score and *Checker 2* uses accuracy score as evaluation metric. When you click **COMPILE & TEST**, the submission is auto-evaluated against the test case that is set as sample checker, that is, Checker 1. A score with respect to F1 score is generated and displayed. ![DS13.png](https://help.hackerearth.com/hs-fs/hubfs/Knowledge%20Base%20Import/DS13-1.png?width=387&height=241&name=DS13-1.png) To make a submission, when you click **SUBMIT**, the submission is auto-evaluated  against the other test cases, that is, Checker 2. A final score with respect to accuracy score is generated and displayed. ![DS14.png](https://help.hackerearth.com/hs-fs/hubfs/Knowledge%20Base%20Import/DS14-1.png?width=391&height=259&name=DS14-1.png) *Note*: If there are multiple test cases, the final score is the addition of all the scores assigned to each test case. The test case that is *set as sample checker* will not be considered in this final score.  When you want to change the score for a data science question, you need to update the score on the UI and in the checker files for correct evaluation. You can implement partial scoring if you want to check a submission with respect to different evaluation metrics. Also, in instances where you have different expected outputs.    - [Assessments: Recruiters](https://help.hackerearth.com/assessments-recruiters?hsLang=en#main-content) - [Getting started](https://help.hackerearth.com/assessments-recruiters?hsLang=en#getting-started) -
