To get a rough idea for HITSEEE ranks :

• For Top 25 rank, you usually need around 100+ marks.

• For Top 50 rank, about 90–100 marks should be enough.

• For Top 100 rank, scoring around 80–90 marks is good.

These are approximate and can change every year depending on the difficulty level and competition. But aiming for these marks will give you a good chance.
