The UCEED content DQ Edge has all and more you would require. You do not need any book.
The advantages of DQ Edge over any book are -
DQ Edge content is updated on a daily basis - so you always have the latest study material. A book is outdated by the time it goes to print
DQ Edge understands you - it will tell you what to study next so you can prioritize and cover all topics in terms of importance and relevance from an exam perspective. A book will only give you a question bank.
DQ Edge will tell you if you have understood a concept or not - With Cognitive Analytics, you will be able to make out which topics you have not understood and helps you study that effectively
