The World Youth Championships will be held in Ukraine in July.
Neena's teammates A.M. Binsy and S. Akshaya completed the other two places on the podium as Kerala pipped overnight leaders Haryana by just one point (155-154) to defend their overall title.
Haryana continued to apply pressure with more number of wins on the last day's events at Brahmananda Reddy Stadium on Monday but the defending champions fought back with vigour and the tale of identifying this edition's champions went till the last event of the meet-the medley relay.
In the medley relay for girls the Kerala team was trailing at mid-way but the last leg runner Shaharbana Sidhique made a gallant effort to take her team to the flag position.
