Gaining masters outside of my degree

Trying to go for a Economics and finance masters degree at Kings college London, but the entry requirements state you have to be from a science/ engineering background.

The modules are introduction to economics etc. My question is, as a management graduate - what is the best way of converting/ filling in that education gap to go to a masters as I don’t have funds for another degree

My questions:
1) do edX certificates help in applications ?
2) is the economics course I am discussing difficult at masters ?

Not entirely sure if KCL does these but some unis will let you take a PGCert/PGDip version of the Masters and if you complete these satisfactorily then they'll transfer you over to the masters program

Thanks for the response. It is not listed but I was wondering, if you stop at a certain point and request to be given a PGDip or Cert instead - is that allowed or even an option ?

Umm i see no reason why not, them being awarded depending on how many units you complete. So i would assume so yes

* fair warning though, that might be different between universities and some programs will have prerequisite modules to be completed so it could still vary
