The most direct answer is that if you have to ask if you are good enough for MBB you probably arent. But that aside, it's easy to determine this - if you have stellar academics, are an insecure, OCD overachiever who thrives on a sort of masochistic cycle of being told you are elite yet need to constantly overperform to prove it, then you should be fine.Basically, if you have the academic to have a chance then go for it. If you arent a 1st class from oxbridge ( russel group at least) and have the extras then you will probably not be successful.Wont hurt to try but dont rely on it.
