What is the syllabus of ISRO Entrance Exam 2011?

After getting many questions from students regarding the syllabus of Isro exam,we have managed to prepare a list of subjects for electronics,computer science branch and mechanical branch.But again we say that Isro has not issued any syllabus for the exam.so this can not be taken as an official syllabus,but it covers all the topics from which questions are asked.
