Tum notes

I'm still in 11th grade in high school in France but I'm trying to get informed in advance about admission to TUM and I want to know what grade in the Baccalaureate could guarantee me 90-100% chance of being admitted to the engineering/CS program. I had seen that 14-16, so converted to the Abitur that's 2.5 or 1.9, is that good enough? But I'm wondering if that can be enough given that I'll be competing with people from all over the world.
