Dear Indu, Never in life get depressed because doing hardwork surely give better result.As i have passed in May 2012 exam both group in first attemp as due to better study n luck .
Just study well and focus on Study material rather than any writter or publiser book
For theory subject read practise manual and almost revise the question asked twice
I have also posted the study plan for ipcc nov 2012 get the plan and work on plan
All the best
