@ Muhammad Ali Chaudhry.
You took all the words from my mouth . I am calm now that you have changed the title . The problem was not that you guys were not making it sticky. The problem was that you guys were not responding and that makes it frustrating. I will be adding more chapters IA. Anyhow these chapters are not special because they are the most important. Quoting post #6 from the same thread: "These two chapters are the most pathetic ones and none of the lecturers have solved them in their notes for BSc"... and this is not my post. rest is up to you, you know the rules better. and anyways this thread is, hopefully, going stay on top for quite some time , so no problems with its stickiness .
