If you buy a Level 5 code, you can also assign the Level 5 audiobook to weaker students in your class, but the comprehension quizzes are locked to the specific level’s CEFR rating (B2 to C1).

| Situation | Do you need a new unlock code? | | :--- | :--- | | Bought a new, sealed book | No. Scratch the sticker. | | Bought a used book from eBay | The previous owner used it. | | Scratched the code but it says "invalid" | No. You just typed it wrong (try 0/O tricks). | | Lost the physical book (but had the code) | No. Log into your Pearson account online. | | Bought an eBook only (no paper) | No. The eBook auto-links to your account. | | Your class requires homework on the portal | Ask your teacher for a new code. | penguin readers unlock code
