Hello Aspirant,

Since you have not mentioned your category so considering it as General but if you belongs to any other category then please mention it down. Also note that admission to either in IIT Tirupati or in any other IITs for B.Tech program is taken only on the basis of JEE-Advance score not on JEE-Main score. But in order to sit for JEE-Advance you need to qualify the minimum cut-off percentile of JEE-Main which will be decided by the NTA at the time of final result declaration.

As we go through the latest cut-off of 2020 then it shows that the closing rank for Open/General category was 4117 for CSE branch in IIT Tirupati. See it is quite difficult to tell you about exact marks to score because for JEE-Advance no maximum marks are fixed but yes with regards to JEE-Advance 2021 if you secure your AIR in JEE-Advance under top 4100 then there are good chances for you to get CSE branch in IIT Tirupati.

You can check out the latest cut-offs from the link given below :-
