Introduction:
When two candidates have the same GATE (Graduate Aptitude Test in Engineering) CSE (Computer Science and Engineering) score, tie-breaker rules come into play to determine their final ranking. These rules help ensure fairness and select the most deserving candidate for further admissions or job opportunities.

Tie-breaker rules:
1. Score in the qualifying degree: The first tie-breaker rule is to consider the candidates' scores in their qualifying degree. If available, the higher the percentage or CGPA (Cumulative Grade Point Average), the better the chances of securing a higher rank. This rule emphasizes the importance of academic performance and rewards those with better educational backgrounds.

2. Score in specific subjects: In case the tie persists, the next tie-breaker is to consider the scores of specific subjects related to the GATE CSE exam. Certain subjects carry more weightage or relevance, and higher scores in these subjects can give an advantage to a candidate. The specific subjects may vary depending on the institution or organization conducting the selection process.

3. Age of the candidates: If the tie still remains, the age of the candidates may be taken into account. The older candidate is usually given preference as it is believed to indicate more experience and maturity. However, it is important to note that this rule may not be universally applicable and can vary based on the specific selection process or organization.

4. Random selection: If all the above tie-breakers fail to distinguish the candidates, a random selection process may be employed. This could involve using a random number generator or a draw of lots to determine the final ranking. The random selection process ensures unbiased selection when all other factors are equal.

Conclusion:
Tie-breaker rules play a crucial role in determining the final ranking of candidates with the same GATE CSE score. These rules consider various factors such as the score in the qualifying degree, scores in specific subjects, age, and even random selection. By following these rules, the selection process can be fair and unbiased, ensuring that the most deserving candidate is chosen for further opportunities and admissions in the field of Computer Science and Engineering.
