Highest package is Rs 21,00,000

No, you have to complete your graduation first. UPSC says that being graduate is the minimum educational qualification. So, get yourself graduated in any field, be it in science, economics, arts, humanities, social sciences or any other of your interest.
I hope it helps.

It will depend on your performance in the interview. But then, you have a fair chance of getting through.

Dear Harvinder,
To become an IPS or IAS officer, you must complete your graduation first. You have to appear for the competitive exam to get into civil services. You can appear for these exams on central level, UPSC and state level. After clearing this exam you can be an IPS or IAS officer.

Do not take a course that has jobs. Go with a stream in which you can do well. Jobs are in every field for those who have skills. Doing engineering will not help, if you end up with just passing without no practical experience earned on your own. For peace in studies, I recommend humanities and social sciences. Just keep your language skills at the best possible level.

You can give the NATA exam after 10th up to 12th. But, it is advisable that you either give your NATA after 12th exams or before you start 12th. In that way, you can concentrate on NATA exams better. From this year NATA will be best of 5 attempts. So, think before you give your NATA.
