It's been a year since I stop reading this manga and decide to binge read when the whole arc is done. So.... is the arc done? D:
The 4 losers of the top8 are fighting for 5th place, the vanguard match is over, next up is the sergeant match. (It will be followed by the finals who knows when) and they just started the touch upon why Teru is shunning Saki. Chapter 154 would be a good place to stop, but since it was released Feb 7, 2016 maybe that's where you left off? XD
Not much happened since then, but still so much happened.
To actually answer your question: no, the arc isn't done.
