Dear Aspirants , the Results of CSE and IFoS Prelims 2021 were announced yesterday. It is a time which brings joy to some and disappointment to others.
But more importantly , it is a time to introspect.
Introspection does not only include recognizing your areas of improvement , but also to APPRECIATE the areas where you performed well. That is from where you derive your motivation and confidence.
Not all factors for this process are in our control.
Preparation is one part of the process , Performance in the paper is the second part and Results are the third part.
The first two are in our control and that is where we should put our efforts. The results will arrive one day or the other.

Geology Optional : We have prepared a list of major themes that have been frequently asked by UPSC in Indian Forest Services Mains Examination , which aspirants can prepare in order to score decent marks without compromising preparation of GS and CSE Mains.
Please utilize this well. Hope it helps.

Answer Writing : These are Mr. Divyanshu Nigam's (CSE - AIR-44 , Geology Optional) attempt of previous year's questions. We can all take a leaf from his page : Practising is the key.

The interview published in Indian express answers many general questions on Indian economy.
It also provides a way on tackling difficult questions in interviews for example the success and failures of demonetisation .
