Hey aspirant,
Hope you are doing well.
JEE is a national level examination conducted at two levels i.e. JEE mains and JEE-Advance.
JEE mains is conducted to get admission into NITs, IIITs and GFTI. The questions of JEE mains are slightly on the easier side. The question paper comprises of two sections: Section 1st contains 20 MCQs and next section consists of 10 subjective questions out of which 5 are to be attempted. The exam is conducted in Computer based mode. You have to qualify mains to be permitted to write JEE-Advance. Last year cutoffs for OBC candidates was 74.31 percentile. It is conducted 4 times in a year.
JEE-ADVANCE is a bit on the tougher side and conducted once after JEE mains and top 2.5 lakh candidates are allowed to write the exam. It is for admission into IITs. For a obc candidate to get admission into IIT a rank around 3000-5000 can ensure you a seat. There is no particular pattern of JEE-ADVANCE paper. It comprises of comprehension, single correct, multiple correct,integer type,match matrix. The basis of these exam is NCERT but you will also need some other books like cengage,arihant to practice the questions and take your preparation to a good level.
Hope this information helps you.
