Computer Science Text books

I really love to study computer Science course. It is very interesting and enjoyable to study. However, in Papua New Guinea the online or internet system provided by ISP’s are very poor. As a result of poor internet service, I am unable to complete the course quickly. The internet rate is also high and I can’t afford to meet the cost. Will it be possible if you can send me all PDF copies of the text books and other supporting documents so that it’ll be easy for me to download them and study. Thank You
