Thank you all so much for your replies! I just got accepted from LSHTM and i think it's the best choice for me! :D
I hope that the employement rates are good because i really couldn't find much! At least academically i think it's the best choice out of the five in terms of biostatistics!

Thank you again all for your replies! :D
