A candidate who has undergone heart surgery can be eligible for the IAS post if they are medically fit and can perform the required duties without any serious health problems The UPSC allows candidates to appear for the exam if they meet the general physical and mental fitness criteria After clearing the main examination and interview all selected candidates must undergo a detailed medical examination by a government medical board If the candidate has recovered well from heart surgery and there are no complications they can be declared fit for service However if the surgery has caused any permanent disability and if it is certified under the benchmark disability rules then the candidate may be eligible for reservation under the persons with disabilities category Final eligibility depends on the report given by the medical board during the selection process

If a person has undergone heart surgery for ASD which means Atrial Septal Defect and is now medically fit then they can apply for the IAS exam There is no restriction for such candidates if their physical and mental condition is stable and they can perform the duties required in civil services However selection to IAS also depends on passing the medical test conducted after clearing the main exam and interview If the person has any lasting disability due to the heart condition and it is certified by a government medical board then they may be considered under the benchmark disability category as per the Rights of Persons with Disabilities Act In such cases the candidate may come under reservation for persons with disabilities in the specific category mentioned by the medical authority It is always advised to check the official UPSC notification and consult with a government hospital for proper disability certification before applying

If you want to become an IAS or IPS officer after completing your 12th in PCMC ,  focus on graduation because the UPSC Civil Services exam requires you to have a bachelor’s degree from a recognized university. You can choose any graduation stream, but many students prefer degrees like Political Science, Public Administration, History, or Sociology because these subjects help build a strong foundation for the UPSC syllabus. it’s not mandatory to pick these; you can also pursue Science, Commerce, or Arts as long as you complete your graduation. Along with your degree,  start preparing for the UPSC exam early by reading newspapers, improving your general knowledge, and practicing answer writing. So, after 12th, pick a degree you are comfortable with, and plan your UPSC preparation alongside
