How to Pass the OET: A Guide for Medicine Candidates

I would find this guide boo for OET even more helpful if the link given for an audio access was working. I tried many times but it says that this channel doesn’t exist. Also, there are confusing mistakes with a numeration. For example, the answer 18 is wrong as this information was given in p.4.. Also, on p.120 is wrong answer for question 11. Otherwise, I would recommend this book.
