I bought this book without knowing anything about it and I’m so glad I did. The book covers all levels of amateur licences in the UK. The way it does it is that each chapter is divided in subsections for each of the levels, so, you can read each chapter up to level you are interested and move on to the next.
Each chapter contains a brief introduction to the subject followed by a set of sample questions like the ones you’d get in the exam. Unlike the American counterpart, the question pool in the UK is not public because you should learn the subject and not memorize answers. Having said that, having some mock tests really helps understand how well prepared you are. There’s even an extra set of questions towards the end.
The answers to all the questions are in an appendix almost at the very end of the book, so, it’s very convenient to avoid accidentally seeing the answer and losing the value of that question. I found thought that going back and forth was annoying and prone to seeing more answers than intended, so, I’d recommend for each section, to do all the questions by writing down the answers on a piece of paper and then checking them against the references.
At the very end of the book you also have the tables, band plan and references that you are allowed during the exam.
I highly recommend this book if you are going to take the exams.
