I am building upscpath.com - a platform which has copies of people who got through. I used gemini to extract content from those copies and somehow indexed it all syllabus wise.
After building it for 8+ months I am finally moving towards monetisation. Any books on entrepreneurship would be helpful as i build this.
UPSC Civil Services exam is one of the most coveted exams in India (https://en.wikipedia.org/wiki/Civil_Services_Examination). I created the platform which has indexed mock test copies of people who are now officers for the Indian Govt.
Now I am building additional features that make the prep slighly easier. The platform is already live and is being used by several thousand aspirants.
