This is level 3 of the I-Tunnel.
In this level, you have to jump long gaps to reach for the next platforms, but there are Conveyor tiles, flowing in all four directions, that can make this level quite challenging.
The Student is good for this, as her ability to float in the air allows her to span the gaps easily, and the risk of overshooting will not exist either. But be careful that on the Conveyors that swept sideways and backwards. They may send you tumble off the platform, or slow you down so much that you can't make the jump even using the ability. Avoid them as much as you can, and even being in the air is better than being on slow conveyors.
The Runner is probably your Plan B(Plan A if you don't have the Student), and when on the Conveyors that slow you down, just keep doing small hops, or do a long jump to stand on the tip of the platform (sometimes it is not a Conveyor tile, it may be a Normal tile), but be careful of overshooting or missing the next platform. If slower speed is needed, try the Skier.
