IIT-JEE 2007 had 2 papers - Paper I and Paper II. The duration of each paper was 3 hours. Each paper consisted of 66 Questions. Both the papers had 3 parts each ? Physics, Chemistry and Mathematics. Each part had 22 Questions.

Each of the three parts - Physics, Chemistry and Mathematics - was divided into four sections. The format of the questions in any given section is the same across the three parts (Physics, Chemistry and Mathematics) and across the 2 papers (Paper I and Paper II).

The details of the sections are given below.

	No. of Qns	Title of the Section	Marks per Correct Answer	Number of Choices	Penalty for Wrong Answer	Maximum Marks for the Section
Section 1	9	Straight Objective Type	3	4	-1	27
Section 2	4	Assertion-Reason Type	3	4	-1	12
Section 3	6	Linked Comprehension Type	4	4	-1	24
Section 4	3	Matrix-Match Type	6	0	0	18
Total	22					81

Total Marks in each part(subject) = 81
Total Marks in each part(subject) = 81 X 3 = 243
Total Marks in IIT-JEE 2007 = 2 X 243 = 486

Categorization of Questions (Easy, Medium, Difficult) for Paper-I

EASY:- Easy Questions are defined as those questions that can be answered by a student who knows the concept under question. It is a direct application of the concept. A student is expected to have attempted all the EASY Category Questions.

MEDIUM:- Medium Difficulty Questions are those questions that may involve more than one concept. A well-prepared student should be able to identify at least 75% of these and solve them correctly

DIFFICULT:- Difficult Questions are those Questions are those will definitely involve multiple concepts and are tricky. The students may be led to think away from the ideal method of problem solving. It will require good effort even from the well-prepared student to identify the Difficult ones and categorize them accordingly.
