Hi,

I hope you are doing well!!

Coaching will give you enough study material as well as guidance from experienced teachers but after a long time, you will not get enough output from these institutes.

There are few good institutes you can trust upon if you are a Hindi medium aspirant like Drishti, Patanjali etc. But still I will suggest if you are a Hindi medium student then you can prepare from NCERT books and make your own notes to make your GK stronger.

These days the Civil Services exams is based on totally current affairs. You can trust on some online sources like Wikipedia (Hindi and English), Sansar Lochan, Vision IAS Hindi Test Series bla bla.

I know there are few sources for Hindi medium students but still you can fully trust on the above websites I mentioned. You should also have knowledge about English because you are going to be an IAS officer. That is why keep searching English sources also for the particular topic you’re searching for.

I hope this helps!
