I just received the book, I will update as I progress, but for now, it's all technical.
The book is printed with poor quality paper, honestly, I'm afraid to ruin it while I'm writing on top of it, that shouldn't be an issue anymore. Secondly, the supposed app that comes with the book is not user-friendly, not attractive, doesn't respond quickly. Thirdly the book is bigger than I thought which surprised me for the best, I don't like when workbooks are small. That's all for now, as I progress with the book I'll update.
