es, entrance exams are a common requirement for PhD admission in India, but the specific exam depends on several factors:

• Different fields might have their own designated entrance exams.
• Each university might have its own entrance exam or accept scores from national-level exams.
  
  
  
• National Level Exams: These are widely accepted by many universities. Some popular ones include:
  
  
  • UGC NET (National Eligibility Test): For various fields like Humanities, Social Sciences, Commerce, Management etc.
    
    
  • CSIR UGC NET: For Science stream aspirants.
    
    
  • GATE (Graduate Aptitude Test in Engineering): For Engineering and Technology fields.
    
    
• University Specific Exams: Some universities conduct their own entrance exams for PhD programs.
