Hi,

Marks you need to score in JEE MAIN to qualify for JEE ADVANCE is given as follows :

General category:

Marks between 100 to 120 would be enough to somehow clear the cutoff.

OBC category: 

Between 60 to 80 would make you eligible for ADVANCE.

SC/ST category: 

You just need marks between 40–60 to clear the cut-off for ADVANCE.

There is no fixed score for cutoff but the range is around 80 to 130.

But for a good JEE Main rank (less than or around 10k) you need to get at least 180+ marks (cutoff being less than 120 marks)

Now, about JEE Advance. 

For a good rank in JEE Advanced, you need to score at least 40% of the max marks (240 out of 400). Though this completely depends on the stream that you choose the approximate range is around 1–4.5k for IIT's.

Hope this helps. You can contact for any further guidelines.
