For total beginners it's probably not a good book to start from. Maybe this book can help.

Whereas Pat Dorsey approaches things heavily from a DCF perspective, What Works on Wall Street makes its approach from a more systematic perspective, and comparing various investment strategies.

Pat Dorsey goes through the super classic stuff (discounted cash flows, economic moat, margin of safety, etc.) where the tools you need to use are basically Excel. There's ways to leverage Machine Learning to pick stocks too.

For investing, and if you have more time and want to understand discounted cash flows, this book is quite good. To apply it you'll need to use a spreadsheet and dig into the financial statements though. It's a bit theoretical in that all stocks have to be valued with discounted cash flows.
