UPSC won't repeat 2013(sudden change), after 2013 UPSC has changed pattern of engg services , combined medical services , that too notifying 1 year before, ( UPSC notified ese 2017 new pattern after 2016 notification)(they know atleast 1 year is needed for preparation, ) , the Hindu published the news article quoting Braintree director, I am sure they are still in hangover of that sudden change of 2013 that's why proposing that UPSC can do this and that . So this is for sure that pattern will be same for 2018, now talking about age, natural justice will prevail, n 2 year freeze and gradual decreasing will be modus operandi, so those who are in late 20s will get sufficient attempt don't worry about that, they already know what type of agetation it could bring if they play with age ,
Lastly from past 2 years around same time of the year, same type of news used to pop up, it used to become hype , news paper , TV channel increases the TRp and then everything used to come back to the same point , baswan committee is not thefirst committee to propose decrease in age limit, 2 nd ARC, Khan committee, etc etc had already proposed the same, though it will be beneficial for country and its youth , but it should n will be in gradual manner providing sufficient window,
don't panic , keep on studying , prepare your optional coz this is the best time to prepare it. Believe in UpsC and believe in urself !
