Hello, I was recently rejected from the jacques hadamard school when I applied for a MSc in Maths, the motive was my unstable initial training, I studied Physics eng. and I am aware of the lack of hardcore maths in the studyplan, for example i dindt take real analysis or topology, etc etc. I did switch my interest from physics to math and is my goal to get into a math MSc. I am looking for ways to strenghen my CV in order to get in, any ideas?
