when you are saying anybody applying Prelims tricks can sail through paper.
Actually the paper has tried to do away with these poor ways to approach Prelims in my opinion.It has given “all of above” for many SnT and Environment ques and at the same time it has used words like “Present” in AI question to keep you on toes.
One had to be vigilant in every question , convince oneself that nothing can be eliminated and then only select all of the above.
As far as polls by Coaching institutes are concerned, I wonder if we are debating about their keys how can we be Convinced with the marks students are getting via their key.I am more particular about students getting 100-108 .They can easily slip back to 95.
