# TISC 25

TISC 2025 lasted 2 weeks from 12-28 September 2025. I solved 10 levels and got 7th place! This was really awesome for me as I went from only being able to solve 3-4 challenges in 2023, to solving 7 challenges in 2024 and finally to solving 10 challenges and being eligible for prize money this year :)
