nt able to score marks in phase tests ..inspite of doing so much hard wok and completing all packages

while doing packages you are not able to see the time and end up spending hours doing 10-20 questions . You need to basically increase your speed which is the most important thing. Second increase the level of your question especially maths and physics. Packages arent enough. A good list is given on this site "http://www.askiitians.com/Important-books-iit-jee.aspx"look at this for book selection.
