Feeling easy with IIT JEE question papers

IIT is one of the most prestigious institutions not only in India but all over the world. At present, it has sixteen branches across the country—Bombay, Delhi, Kanpur, Kharagpur, Madras, Guwahati, Roorkee, Hyderabad, Patna, Bhubaneshwar, Ropar, Jodhpur, Gandhinagar, Indore, Mandi and Varanasi. Seeking admission to these branches is very hard and only brilliant and talented students can crack it. The degrees awarded by IIT are equivalent to any degree awarded by world-famous institutes.

When it comes to entrance examination of IIT, it comprises two parts—JEE Mains and JEE Advanced. The former is a preliminary stage and the latter is the final stage. Both have different syllabi, and candidates need to have a thorough preparation to crack them. Candidates, who qualify the former, are eligible for the latter.

When it comes to IIT JEE question papers, they are set for two different stages of examination— JEE Mains and JEE Advanced. There are three subjects in these two stages of examination—Physics, Chemistry and Mathematics. Questions asked from these subjects are very difficult. So, candidates need to work very hard to crack the test papers of these two stages of examination conducted by IIT.

IIT JEE Mains is the first stage of examination conducted by IIT. IIT JEE Mains papers comprises three subjects—Physics, Chemistry and Mathematics. The papers are set in both English and Hindi to enable both English and Hindi medium students to take this exam easily. Multiple choice questions are asked in all three subjects and the duration is three hours. There is negative marking for incorrect answers. So, candidates should not try their best guesses if they are not 100% sure to answer the question. Some of the questions asked in three subjects include the following:

Physics

Time (T), velocity (C) and angular momentum (h) are chosen as fundamental quantities instead of mass, length and time. In terms of these, the dimensions of mass would be

Chemistry

Excess  of  NaOH  (aq)  was  added  to100  mL  of  FeCl3  (aq)  resulting  into2.14  g  of  Fe(OH)3.    The molarity of FeCl3 (aq) is

Mathematics

Let f(x) =210⋅x+1 and g(x) =310⋅x−1.  If (fog) (x) =x, then x is equal to

These questions are just a tip of the iceberg of the IIT JEE Mains papers. Candidates, who pass IIT JEE Mains, are eligible to take IIT JEE Advanced. This is the last stage of IIT entrance examination. Those who pass this stage are selected for undergraduate courses taught at IIT. The papers of IIT JEE Advanced are tougher than IIT JEE Mains papers. There are thirty multiple choice questions in each of three subjects—Physics, Chemistry and Mathematics. There is negative marking for incorrect answers. So, candidates should not make guesses. For instance—some of the questions asked in threes subject include the following:

Physics

A physical quantity P is described by the relation 12342P  a b c d−= If the relative errors in the measurement of a, b, c and d respectively, are 2%, 1%,3% and 5%, then the relative error in P will be

Chemistry

Based on the compounds of group 15 elements, the correct statement(s)

(A) Bi2O5 is more basic than N2O5

(B) NF3 is more covalent than BiF3

(C) PH3 boils at lower temperature than NH3

(D) The N−N single bond is stronger than the P−P single bond

Mathematics

For a non-zero complex number z, let arg (z) denote the principal argument with− π < arg (z) ≤ π. Then, which of the following statement(s) is (are) FALSE?

Like above, there are many questions which are asked in IIT JEE Advanced papers. Candidates are advised to solve previous years’ papers as many as they can. Doing this will make them competent enough to crack IIT entrance examination with flying colours.
