The final race of the weekend at the Hungaroring is due to commence at 17.40, with JHR Developments' Kai Daryanani set to start from pole.
Race three features a top-12 reversal of the combined qualifying result, and Daryanani was 12th in that classification, and therefore starts from reverse pole for the second time this season.
Alongside the Indian on the front row will be Elite Motorsport's Flynn Jackes, while Argenti with Prema's Reza Seewooruthun and VRD Racing's Hugo Schwarze will fill row two.
Next up is Rodin Motorsport's Abbi Pulling and Xcel Motorsport's Patrick Heuzenroeder, with race one podium finisher Will Macintyre (Elite) and Hitech's Deagen Fairclough.
JHR's Noah Lisle and Rodin's race one winner Gianmarco Pradel complete the top-10, with qualifying pace setters Keanu Al Azhari (Hitech) and championship leader Alex Ninovic (Rodin) starting from 11th and 12th.
Jack Sherwood has been handed a three place grid penalty for race three, for his part in the turn one collision at the start of race two.
