Hello,

Based on previous International Mathematics Olympiad (IMO) results and trends, scoring 45 marks in Class 12 can place you in a relatively high rank, often within the top 5% of participants, depending on the difficulty of the paper and overall student performance. In the 2023-24 IMO, a score of around 42–47 marks in Class 12 was close to the top cutoff for Level 1, making students eligible for Level 2.

Typically, this range corresponds to ranks near the top state or zonal levels but may vary due to tie-breaking criteria like section-wise scores.
