Here is the link for your revision of Unit 4 - The Mass Media. I designed it as a 60-minute test but don't worry, just enjoy your journey!

There are some things that you have to bear in mind before accessing the link:
1. You are allowed to take the test in 60 minutes.
2. After 60 minutes, the form will be automatically closed and you can't do your test anymore.
3. You have to sign in your email to receive the link.
4. Remember NOT to fill in the "skip this field" place.
5. You can only access this test 3 times.

Are you ready for the test? Now, let's get started!
