That's how I learnt programming (self study) as a high schooler more than 2 decades ago: by studying books (affordable fast internet connection wasn't a thing at that time). Start from chapter 1, study the concepts and play with the code examples a few times till you understand. Usually there are exercises at the end of each chapter. Try to work on those.
