Hi @Clara.travaglianti, and thanks for reaching out! 
If you didn’t find any tasks on your homepage, it simply means that there are no available tasks in your language pairs.
And If you’d like, you can sign up to receive daily task stream emails. You will receive an email when tasks are available in your language pairs. 
As far as I know the test to become a verified translator is no longer required and your verification will depend on several good reviews and feedback.
You can find out more on this thread 
Have a great day! 
Best regards. Lilav.
