There are plenty of good, free online CS resources. Check out this page: https://github.com/vhf/free-programming-books/blob/master/free-programming-books.md https://github.com/vhf/free-programming-books/blob/master/fr... Also, have a look at MOOCs on platforms like Udacity, Coursera, edX, etc. Personal recommendation: read "Structure and Interpretation of Computer Programs" (https://mitpress.mit.edu/sicp/ https://mitpress.mit.edu/sicp/, you can get an epub elsewhere). It's one of the most important books around, MIT uses it for their introductory CS course.
