The Joint Entrance Examination Mains -

It is conducted for admission for undergraduate Engineering program i.e. B.E/B.Tech at NITs, IIITs, and Government funded Institutes.

Most Probably the minimum marks required in JEE Mains are on the following-

Category Cut off (percentile)

• General                           88-92
• OBC                                  70-72
• SC                                     48-50
• ST                                     34-38

It is basically determined by the number of student appeared for examination, difficulty of exam, no. of seat in colleges and many more.

Hence the students who secured more than or equal to minimum qualifying marks will get eligible for JEE Advance.

Joint Entrance Examination Advance -

It is conducted for admission for undergraduate Engineering program i.e. B.E/B.Tech at IITs.

The cut off marks for JEE advance is basically depends on many factors, first and foremost students have to secured minimum marks in each subject (Physics, Chemistry, Mathematics) along with students have to secured minimum aggregate marks.

Most Probably the minimum marks required in JEE Advance are on the following-

Category Subject wise (Marks)            Total Marks

• General                           6-8                                         61-64
• OBC                                  5-7                                        54-58
• SC                                     3-5                                        30-34
• ST                                     3-5                                         28-32

Note: If a student secured minimum aggregate marks but failed to get required minimum marks in any particular subject then he/she will not be considered for admission to IITs .

Well taking particularly about IIT Madras. It is one of the top ranked IIT, the minimum ranked required to get into IIT Madras is under 6000-7000. if the student wants his/her desire branch then he/she must secured all india rank under 2000-2500.

hope this information will help you.

Analyzing the previous year data, below I have mentioned previous year cutoff percentile for different categories for JEE(advanced).

• General - EWS :     66.2214 %ile
• OBC - NCL :     68.0238 %ile

For your second query, previous year cutoff says; To get into IIT, you need a minimum of 5% of marks(around 56 marks) in each subject you have appeared for in JEE Advanced paper (for OBC Category).
