Hello Maria!!
I decided to go Bradford University, finally..
Between these two unis, Aston & Cardiff as I see in rankings Aston is higher almost in all rankings.. But I have already made a mini search about Aston..about Cardiff I dont know much..
You can look if both have the triple-accreditation, Aston has this.
You could also try to speak with students from these unis from the master that you are interested to.. this was very helpful! For me facebook search machine worked well and I found many students and spoke with them before I decide..
otherwise ask the International office of the university..but they will not suggest you too many students..
It is very attractive that Cardiff has the opportunity instead of doing a dissertation to solve a real marketing problem..and also Cardiff uni is member of Russell group and some guys told me that there will be many events with managers or companies.
On the other side Aston has a very good reputation for business for Cardiff as I told you I dont know...
maybe it has also... speak with students from there!
a! Aston gives opprtunity for erasmus exchange in some masters..
Moreover, maybe you have to think the city..I believe that Cardiff is more beutiful, with sea at close...than Birmingham.. but Birmingham is one of the biggest cities with many oportunities for job after..
I have the same dilemmas and I believe that I didnt helped you much with my comments.. it is a really difficult choice!
I dont know much for Cardiff..but for Aston everyone that I spoke to was satisfied.
The most advices for me were to look the content of the master and which is more attractive and interesting. You should try to think which master do you like most..
and my advice...with which of these two... was "love at first sight"... has this click for you.. (I cannot write in greeks but you understand our expression i guess
)
Also ask these unis how many students are working 3 months after they finished..? a percent or something..or search on internet..there are some rankings for this too..or ask the carreer service of these uni and compare their answers or even how quickly they respond..
I hope that I helped you a little bit
Good luck with anything that you will do!!
for any question do not hesitate to ask again!
