If you like learning, you will find some amazing free resources on the Internet for pretty much every topic under the sun. Although there are many great learning websites these days, I want to particularly mention Khan Academy, a not for profit website designed to help you learn without spending money or having to step outside your doorstep.
Khan Academy is a website that has a vast library of material covering a wide range of topics from science to accounting, to all kinds of mathematics. Just type in the subject you want and it will bring you to the related material you are looking for. You will find informative videos that are very well put together. You will almost feel like you are sitting in a classroom.
