Need a suggestion.

Hi, There I'm 25 year old dude, Working in IT Industry. Currently making 13.5Lpa in Noida. I'm thinking about preparing for SSC and aiming for ASO or Income Tax role. I work in hybrid mode and get around 4-4.5 hours in spare which I can use for preparation. So i need to ask is it feasible to prepare for CGL 2025 with such less time? I have tried some mock tests without any preparation I'm getting somewhat around 110-115. What should be a realistic stretegy. Since getting a good rank for these posts are hard. Should I prepare for CGL 26 instead for 25? What are some good source to learn, Mathematics is not something I'm worried about. Have no idea about other subjects.
