+# The certification process
+
+
+The certification process is **completely free**:
+
+- To get a *certificate of completion*: you need **to pass 80% of the assignments** before the end of April 2023.
+- To get a *certificate of excellence*: you need **to pass 100% of the assignments** before the end of April 2023.
+
+
+
+When we say pass, **we mean that your model must be pushed to the Hub and get a result equal or above the minimal requirement**.
+
+To check your progression and which unit you passed/not passed: https://huggingface.co/spaces/ThomasSimonini/Check-my-progress-Deep-RL-Course
+
+Now that you're ready for the certification process, you need to:
+
+1. Go here: https://huggingface.co/spaces/huggingface-projects/Deep-RL-Course-Certification/
+2. Type your *hugging face username*, your *first name*, *last name*
+
+3. Click on "Generate my certificate".
+ - If you passed 80% of the assignments, **congratulations** you've just got the certificate of completion.
+ - If you passed 100% of the assignments, **congratulations** you've just got the excellence certificate.
+ - If you are below 80%, don't be discouraged! Check which units you need to do again to get your certificate.
+
