All Mario Circuit Question Mark Panel Locations

Question Mark Panel 1: Located on top of the lower roof of the building to the left of the starting flag. Enter the large warp pipe next to the starting flag, ignore the spring, and drive around the edge of the building. You will find the panel between two fans.

Question Mark Panel 2: Situated on the highest roof of the same building. Enter the large warp pipe next to the starting flag, drive over the spring, and use the green rails. Perform a trick on the raised part of the rail to reach the roof rails. Stop your momentum to get off the rails and drive over the panel in the center of the roof.

Question Mark Panel 3: Start at the starting flag and take the green road to your left. Follow this onto the main road, turn right (north), and continue until you reach another green road on the right. Take this road to the Repair Service building. The panel is on the floor between the two Nabbit Courier trucks parked outside.

Question Mark Panel 4: This panel is on a raised piece of grass. Take the same green road used for panel 3, but travel towards the colored barrier ahead (where the warp pipe is). Charge your jump beforehand and release it when you reach the barrier to land on the raised land. The panel is on the grass behind the antifreeze sign.

Question Mark Panel 5: Drive past the Nabbit Courier trucks (on the same path as panel 3). Across the road is a Natural Oil Banana sign. Charge your jump and release it when you reach the sign to get above the area. Follow the grassy path to the right to the end to find the panel.
