From IT Jalakam - Unofficial IT syllabus for grade 10 students

The theme of the course is - IT for the common man. As hammerhead from the TE forum wrote - "It is crucial that you make people realize that computers are not some fancy machines only for the elite, the rich, the young or the modern. You have to highlight the fact that technology is for everyone and makes life easier."
