How to Prepare International Law for UGC NET Law Exam?  

When approached systematically, International Law can be a manageable subject during UGC NET Law preparation.  

Based on the subject-weightage, important topics, and type of questions asked, we have a preparation strategy for you.  

Phase 1: Clear Concepts for Strong Foundation (Weeks 1-2) 

The first step is to build a strong conceptual foundation. Begin by understanding the basic nature, scope, and sources of International Law before moving on to advanced topics.  

You can refer to standard books such as:  

• J.G. Starke's Introduction to International Law (widely recommended for fundamentals) 
• Satish K. Sharma's Public International Law (exam-oriented and student-friendly)  

While studying, create a topic-wise checklist and track your progress. 

Phase 2: Solve Sectional Previous Year Question Papers (Weeks 3-4)  

Once your concepts are clear, start solving previous year UGC NET Law questions. Make sure to practice:  

• Topic-wise PYQ practice  
• Frequently repeated concepts and doctrines  
• Questions related to treaties, conventions, organizations, and landmark cases  

During practice, you'll notice that many International Law questions are direct and focused on:  

• Important conventions and treaties  
• UN and ICJ facts  
• Recognition theories and legal doctrines  
• International Humanitarian Law principles  

Create a separate notebook for recurring questions and revision points.  

Phase 3: Revision and Quick Recall (Week 5) 

The revision phase should focus on high-yield facts, doctrines, and concepts rather than detailed reading.  

Short notes, flashcards, and one-page revision sheets can be particularly effective during this stage. You should create them in the early phases only, so you have them handy when it’s time for revision.  

Phase 4: Attempt Mock Tests (Final Days Before Exam)  

In the final phase, shift your focus from learning new concepts to improving accuracy and exam temperament.  

Make sure to:  

• Attempt subject-specific mock tests  
• Practice mixed-topic MCQs  
• Analyze mistakes after every test  
• Revise weak areas identified during mock practice  
• Focus on speed, accuracy, and elimination techniques  

The goal is to become comfortable answering factual and concept-based questions within a limited time.
