i have not concentrated on iit syllabus in first year .how can cope up to get through iit 2012 exam?

A proper & genuine hard work and self confidence will take you to the peak of your dream. As you must have heard some of motivating quotes like "Push yourself as no one else is going to do it for you" or"Practice makes a men perfect ". There are many people who have taken crash sources, proper study material & test series
good luck!
