i need some advice in deciding which masters degree to choose

Ive gotten an acceptance from

CEMS program(international management) offered by the university of Sydney
Msc finance university of aberdeen
Msc International business queens university belfast
Msc finance queen mary university london
Msc project management (warwick)

Im waiting on a reply from ANU, Melbourne & strathclyde (all of them ms finance)

which program would you recommend in terms of networking and job placement

These are very different. What are your goals? Is Aberdeen a CFA partner programme?

yes its a partner institution , i want to seek a graduate role

Well, I guess Sydney and Melbourne may have the best outcomes, followed by Strathclyde and QMW. Looking at http://rankings.ft.com/businessschoolrankings/masters-in-finance-pre-experience-2015 It seems that Strathclyde has excellent exmployment rates. Maybe focus on an MFin and then do an EMBA in ten years?

could you tell how big of a role do level grades play in attainment of a job upon graduation in england

Undergraduate grades matter a lot in getting into masters programmes but at the masters level employers typically focus on a small number of schools rather than students with high grades across a large number of schools.

thank you but I'm coming straight out of a bachelors with no work experience

If you take an MFin then the school matters more than the grades. That is still my point.
