I have been in the habit of searching web links on topics I couldn't find much information in books or were too theoretical. In this process, I made a list of URLs which contain useful stuff in a good language. I am posting these URLs for all my friends who are aiming to crack the NUT errrrrrr NET :-)
I am not boasting of providing best of links but just want to say I got good help from these URLs.
All the best for December' 15 Exam!
