Whoever says KCL is **** are actually very misleading and just dumb themselves and have an inferiority complex and felt that the only way they could be appreciated as a person is through education.
It's on the same level as Bristol, York and Edinburgh pretty much, which is still damn prestiguous and highly respected.
But when we're talking top of the top of the top uni's, we're really talking oxb, imp, ucl, warwick, lse, and maybe durham.
