Guys never ever think in any of 8 papers of completing 100 marks paper... even if you can complete 80+ marks paper with above average confidence then, you can easily get 50+ in all the 8 papers...
About AMA:
May 14 was difficult and lengthy both... whereas
Nov 14 is lengthy only... (Ya agreed for 2/3 difficult questions but, most of sums were from PM and SM Directly...)
So it is wise if you have completed 70+ marks paper... you will clear.. now please focus on ISCA...
