The Microsoft Office Specialist is a brilliant study guide for the MOS Exam. This is a HUGE book to work through but don't be daunted by this as it is well written giving clear Concise instructions in every aspect of Word, Excel, Access, PowerPoint and outlook. There is a disk with practice files on which has to be installed onto your computer but I do recommend that once you have passed the exam I would delete them as they take quite a large amount of space on your hard drive.
I bought this book just to refresh my skills in the microsoft office package and I had no intention of taking the exam, I now have decided to go for it as this book is an excellent aid for studying this exam.
I cannot recommend this book highly enough, it is interesting and very easy to follow. If you work through this book from beginning to end you will pass the exam with flying colours. WELL DONE MICROSOFT!!
