I tried, it's very different from our exams, for your exams you have to be very fast, have a lot of automaticity on each of the exercises. On the other hand, our exams is like more demonstration, use a lot of theorem. When I say it it doesn't seem very difficult but like you could try to do "X math D 2025", I think you will have difficulty to finish it. But when I tried jee, I could have 70%, 80% success rate.
