I’m writing regards the Gold C1 advanced ISB 978-1-292-20291-8 book. I’m studying CAE English and your book is recommended by the college. I’m very disappointed with your book, especially spending more than 40£ on this book. You don’t think about dyslexic and colour-blind people. Text is hard to read, in some places, it’s not visible at all. Why are you using handwriting style fonts, which are unreadable by dyslexic people? Another example, on page 11 you have a brown letter on the black background? Do you think it is easy to read not just for colour-blind people even for ordinary people it would be hard to read. All exam tips boxes are on dark background and with dark text. The Paper, it’s printed on is very glossy and making it’s impossible to read under the desk lamp as it’s all reflecting. Absolutely disgusting book, not pleasant and not convenient to use. This coursebook doesn't have any content table and makes it's harder to navigate inside the book. Makes me feel you think more about profit neither your customer. Gold C1 advanced Exam Maximiser is far much better.
