Government & Defence Entrance Exam

Hi,
B.Tech has nothing to do with civil services and there is a separate examination to become civil servant. However, for some experienced position they prefer engineering graduate or post graduate.

Hi,If you have decided to become an IAS officer, then Humanities (Economics, History, Public Administration, Sociology etc.) subjects are recommended. You may also opt for legal studies. However, choose as per your interests, there is no specific requirement.

This is not a problem.
Just opt a degree of Computer Science, study for 4 years. If your mind change to stay in the computer science, then go ahead and if not, then go for civil service by giving examination after graduation.
Don't be confused, go for CS, and then for civil services.

After your Bachelor's degree, you can apply for the civil exam. There is online registration for civil exams.

Hello Devi,
Can you please elaborate your question? What you are asking is not clear.

After clearing CDS you can continue with your regular studies until you join training at IMA or OTS. Once you join training at IMA or OTS, you may continue with your studies on completion of your cadet training as external a candidate. You may not get any leave to appear for examination after training starts. You can appear in exams as external candidates during official breaks or holidays in training. Once, you get commission, you can take necessary approvals from your Commanding Officer to continue with further education.
