Tips to cross 99 Percentile in DILR

When I had appeared for CAT 2025 Slot 1, I got 98.04 percentile in DILR, without any serious Prep.

I have taken Career Launcher Mock Test Series, and I am able to solve only 1 set correctly in each Full Length Mock.

Either it takes too much time to solve a Set, or I need to look for Solution afterwards.

What should I do so that I could easily cross the 99 Percentile Mark in CAT 2026?
