As UPPSC aspirants protest for 2nd day, U.P. govt. faces flak

Thousands of youth are protesting outside the UPPSC headquarters in Prayagraj against the conduct of Civil Services (preliminary), Review Officer/Assistant Review Officer examination in multiple shifts and against normalisation of score. UPPSC argues when exams are held on multiple days or shifts for a single recruitment notification, the score normalisation process is essential in evaluating the results as the difficulty level of the paper in each shift/day varies.
