sense?

Bad day. Not from the outside, sun is shining, but inside I am struggeling.
Here I am, attending the top Business School of Germany, Studying abroad at the best School in Latin America, did a good job at the last internship in Singapore. So what? My Prediploma (somehow like the Bachelor, but not really) spit out a bad grade. This grade is what I am measured by in the WHU-world, in the world of applying for the summer internship, the world of maybe finding your employer even before fininshing the degree. This grade says: Florian is an underachiever. Don`t take him. Although he has personality, proved to have analytic skills, is a fast thinker and social skills. His grades are bad, so don't even invite him for an interview. Wasted time.
This is quite a downer for my self esteem - being where I want to be, doing what I want to do, but not really rocking it. Does it make sense to be on this path when you are not one of the best 10%? Will it turn out to be the right decision? Will I end up somewhere happy and wealthy? Goddamn, I hate that pressure. Give me some comments to cheer me up, get me back to the ground or just leave your opinion.
