Hey Vikas,
The civil services exam is conducted by the UPSC every year in order to recruit officers into the Indian civil service. There are a host of services candidates can get into. But the most coveted ones are the Indian Administrative Service (IAS), the Indian Police Service (IPS) and the Indian Foreign Service (IFS). The UPSC has introduced changes in the pattern in recent years that were met with both resistance and open armed-welcome. The most recent change was in 2015 when the CSAT was made a qualifying paper buckling under huge pressure from aspirants. Again, there are several rumours going on about possible changes further. But no changes yet.
Good Luck.
