UT Class of 2025 - Mathematics major

DS is an Auto-Admit to UT. His stats are as follows

Class Rank: 38/1380 (2.9%)
SAT (with Sub Scores) - Not taken (going test-optional)
ACT (with Sub Scores) - Not taken
Major/College of Choice: Math (1st Choice)
Plan 2 or Economics second choice.

My question is - How hard is it to get into Math major as an auto-admit? Is there any place where I can find competitiveness of each major in CNS?
