@Eleni Palmos I have this book too, and it is for beginners - but as @swojnicz mentioned, it is a little out of date now, not sure if they’re claiming it’s been updated?

it was definitely a few years old but would the basics have changed that much?

It probably depends on what areas/modules you would be interested in. The basic accounting stuff (booking a Bill, Journals etc.) probably hold up other areas where there's been more development would not. Sorry I've not looked at my copy for a couple of years!
