thankyou very much for ur information can u tell from where to prepare for ge wat and pi.  

Reading a lot on general topics and hot topics will help you a lot for GE and WAT. Sources:
*Newspapers like The Hindu, TOI, Hindustan, etc
*Magazines such as Frontline will give you perspective pertaining to a number of topics that might be asked anywhere in GE, WAT or PI. Try to read Frontline or any such magazine of past 5-6 months. (Not the entire magazine but any page where discussions or view point has been given of a delegate)
*Your own academics curriculum. Try to cover the basics of as many subjects as possible. Interviewers now have a tendency of dwelling deep into any topic that they might pick.
*Prepare HR questions well like your strengths, weakness, a challenging situation in your life and how did you overcome!
*The ultimate mantra to crack GD-PIs is a confident portrayal of oneself. You might not know everything but whatever you know must be confidently presented.
All the best!!
