It is technically possible to pursue improvement for your fourth semester M.Com exam while applying for PhD or JRF at Calicut University.

• The key factor to consider is the timeframe between:
  
  
  • Improvement Exam Application: The deadline for applying for the improvement exam.
    
    
  • Improvement Exam Result Declaration: The date when your improvement exam results will be available.
    
    
  • PhD/JRF Fellowship Start Date: The date your fellowship or PhD program starts at Calicut University.

Challenges:

• Uncertainty in Dates: The exact dates for these events (application deadline, result declaration, fellowship start date) might not be readily available yet. You need to gather this information from the university websites or relevant departments.
  
  
• Potential Delays: Improvement exam results can sometimes be delayed due to unforeseen circumstances.
  
  
  Improvement Exam: Contact the M.Com department at Calicut University to inquire about the application deadline, registration process, and expected result declaration date for the improvement exam.
  
  
  • PhD/JRF Programs: Research the PhD or JRF programs you're interested in at Calicut University. Look for information on the application deadlines, selection process, and expected start dates for fellowship or PhD programs.
    
    
    Compare Timelines:
• 
  
  • Once you have the information for both the improvement exam and the PhD/JRF program, compare the timelines.
    
    
  • Ideally, the improvement exam results should be declared well before the start date of your fellowship or PhD program to allow for any necessary adjustments (e.g., informing the university about the improved marks).
