Main championship

For every race the points were awarded: 31 points to the winner, 27 for runner-up, 25 for third place, 23 for fourth place, 21 for fifth place, 19 for sixth place, 17 for seventh place, 15 for eighth place, 13 for ninth place, 11 for tenth place, winding down to 1 point for 20th place. Lower placed drivers did not award points. Additional points were awarded to the fastest qualifier on Friday (1 point), the fastest qualifier on Saturday (1 point), any driver leading at least one lap in the race (1 point), the most improved driver from start to finish (1 point) and the driver setting the fastest lap (1 point). So the maximum for one driver in one race is to earn 35 points. Oval races only saw one qualifying. C2-class drivers were not able to score points in the main class.

Note:

Race 1 Alfred Unser and David Sterckx only awarded with half points, because they ran non-parity engines. Alfred Unser 3/2=1.5 rounded up 2 points. David Sterckx 11+1=12/2=6 points.

Race 3 only one additional point for the qualifying - oval race.

Race 4 and 5 only one additional point awarded to the fastest qualifier, because only one session was held for each race.

Race 11 no additional point awarded to the most improved driver, because the most improved driver was C2-class driver Cam Binder.

In all races not all points were awarded (not enough competitors).

C2-Class championship

Points system see above. But additional points only awarded for the fastest qualifier.
