Some local unis offer 1 year (inclusive of short sem) master by taught course. You most probably have to call them and ask around. If you ask me, this route should be the fastest/easiest for most people even if the master course is 1 and half year. Research mode is just too unpredictable.

It is also possible by research mode but there are some strict KPI's to be fulfilled and have to get good supervisor who is not looking for potential slaves.

PS: My opinion is based on social science courses

And you are saying, because your university wants to attain a high rating in research, the university does not have many “good” supervisors for you to choose from. Are the supervisors' characteristics directly dependent on your university's rating in research?
Let's see: 3 months to produce a draft paper of 10~20 pages. That roughly translates to 12 lines in a page per day. What would you like to have happen when you have a “good” supervisor around you?

True! It is not easy to publish in ISI journals. However, a good supervisor should be able to tell the likelihood of acceptance of your paper. Your research has to be novel or at least involves a contribution to knowledge. By the way, what is your research interest?
