You might wonder: Why play the Classroom 6x version when I can buy the Steam version? Because of the leaderboard integrity.
The Classroom 6x "Full" version often has a distinct physics engine (slightly floatier jumps) than the commercial release. As a result, a dedicated community of "School Speedrunners" has emerged.

In the "Hell" vertical shaft, there is a section with crossfire lasers. Instead of waiting for the cycle, wall jump continuously. The lasers cannot hit you if you are stuck to the wall's hitbox. This is a glitch that works perfectly in the Classroom 6x full version.
For 80% of the levels, you should never let go of the Right Arrow key. Once you learn the timing of jumps, keeping horizontal momentum full-throttle saves crucial milliseconds. You might wonder: Why play the Classroom 6x

The premise is simple: You control a small, fast-moving cube or character through a series of obstacle courses. The catch? You have a strict time limit, and almost everything kills you in one hit. Spikes, saws, lasers, and falling blocks are your enemies. Your goal is to reach the end portal as fast as possible, shaving milliseconds off your best time. Unlike casual platformers
