It’s great when one can learn how to program for free. Thanks to freecomputerbooks.com, everyone can now learn for free. Previously, there was a similar entry on another website which also provided free IT tutorials . On the main page, we can see the tutorials classified into 9 different categories. The more common subcategories are listed out next to it. Looks very detailed to me. Here’s a screenshot for a better description.
Take look at the website for yourself! Have fun learning!
