Hello Arzo,

Many educational websites provide last year question papers of many universities so you need to check if they can provide you with MA (international relations) one of the websites is bullseye, you can even check on careers360 official website. 

Moreover as far as the syllabus is concerned

• Prepare current affairs

• International organizations and summits
• World relations 
• Environment and related protocols
• Political science
• Political structure of few countries
