Hi Sharmi,

It totally depends on your interest as CBI and IPS both are very respectful and have different working structure. IPS is the head of police department of a city or a constituency. CBI is Central Beuro of Investigation that investigates more complex cases than those which are handled by police.

It is up to you which one to choose.

Feel free to ask doubts in the Comment Section.

I hope this information helps you.

Good Luck!
