The IIT JEE 2012 is the most sought after entrance exam which helps you to seek admission to the various branches of BTech. This entrance exam is broadly divided into four categories such as Chemistry, Physics, Mathematics and Aptitude test.
It is extremely necessary to be aware of the syllabus of these examinations and prepare yourself properly for the exam. It will help you to score well in the examination and achieve your career goals. There are many centers across India which provide coaching and prepare the students for scoring well in this entrance exam.
Examination Pattern:
The IIT JEE 2012 is broadly divided into two papers. Both the papers consist of the questions of Mathematics, Chemistry and Physics. For solving each paper you would get three hours. In paper one there would be about eighty four questions which would consist of twenty eight questions for each category which would make a total score of about 252 marks for this paper.
In paper two each section consists of nineteen questions with a total of about fifty seven questions. The total marks which can be scored in this paper are about 237.
Eligibility:
The eligibility for appearing for the IIT JEE 2012 is passing the final examination of 10+2 pattern which is conducted by any recognized State Board or Central Board. The candidate should also pass the three or four year Diploma recognized by the State Board of Technical Education or AICTE. The candidates who successfully clear out the screening test are qualified to appear for the Main Examination.
