What was new in IIT-JEE 2010 in comparison with earlier years – Paper 1:
NO partial marks are awarded for correct answers in Multiple Correct Type questions. Last year there were partial marks

Part 1 – Chemistry
This is a moderate level paper leaning more towards easy level of difficulty. The usual weightage of Physical > Organic > Inorganic Chemistry is maintained. Most of the questions in this paper evaluate the conceptual clarity of the student

Part 2 – Physics
Overall the difficulty level of the paper was moderate. Still there were a few numerical questions involving elaborate mathematical calculations making them time consuming and hence difficult. No representation of Optics in this paper. Major focus in this paper was on Mechanics (for a total marks of 31)

Part 3 – Mathematics
Mathematics part of the 2011 JEE paper 1 was considered easier than the paper 1 of 2010. Few questions in Integer answer type require in-depth understanding of the concepts with perseverance in solving problems. Trigonometry had a good representation in the paper; the passage on matrices required quick thinking to interpret and solve the questions. One question about ‘3 3 non-singular skew symmetric matrices’ has a basic flaw since odd ordered skew symmetric matrices are always singular. As shown below paper 1 was a moderately difficult paper.



Paper 2

Paper 2 had 60 questions in total – in the order of Chemistry, Physics and Mathematics. Each subject had 20 questions and as in paper 1 the pattern was exactly the same across the subjects. Questions had differential markings, each subject had 80 marks and the maximum mark for the paper was 240.

What was new in IIT-JEE 2011 in comparison with earlier years – Paper 2:

For the first time Multiple Answer Type, Integer Answer Type and Matrix Match Type appeared in one paper.
Part 1 – Chemistry
Paper 2 of IIT-JEE 2011 was difficult compared to paper 1. Weightage wise the Physical > Organic > Inorganic formula is maintained. Generally the nature of the questions in Physical chemistry is calculation oriented and hence the difficulty. Also complexity of Organic questions made this paper a challenging one.

    I expect a total of 85-90 marks . Is there any hope ?
