I'm making a site to help people to prepare computer operator and computer officer exams. Since these exams are objective, I've tried to present as many multiple choice questions as possible. Similarly, class notes and some fee download ebooks are there.
I request you all to help me by sending the useful materials (MCQ collection, class notes, ebooks etc) if you have any to firstname.lastname@example.org.
