Hii student,

82.2% is actually a good percentage from ICSE BOARDS. You can pursue both the career options. One of the best way to join Indian Army is through NDA examination that you can appear, just after completing your higher secondary education. You can be an IAS officer by cracking UPSC examination but will need to complete your graduation first to appear for the same.

Both has bright prospects and gives you a chance to serve the nation.

Best of luck for your future.

Hope it helps!!

Hello,

Well, it depends on your areas on interest, nobody can decide on your part, usually for both the exam eligibility criteria remains the same, which is Bachelor's Degree in any discipline from a recognized university, both the fields and their respective jobs are highly dignified, the syllabus of UPSC is more extensive compared to Indian Army, this is something that can be your point of consideration, as you'll have  to study a lot for UPSC and if you don't like reading humanities subject, you'll find the preparation process tiring.
