Brain Test 5 Level 18 restores order to a chaotic classroom by dealing with one disruption at a time — separate fighting students, address the next problem with the new prop, and wake the sleeping student.

Board Notes

Layout: Level 18 opens in a classroom with students at wooden desks, a teacher at the front, and multiple students causing disruptions — arguing, passing notes, or falling asleep. Multiple characters are visible simultaneously on screen.
Goal: Multiple sequential classroom disruptions must be resolved. Each part has one target student and one new interactive prop. The level ends when all disruptions are handled and the classroom is quiet.
Opening: Part 1 — two students at the front are arguing or fighting; drag the cat that appears toward them to distract them, or drag one student to a separate empty desk. Part 2 — a different student causes trouble; apply the newly appeared prop to that student. Part 3 — a student shows z-z's (sleeping); tap them or use a nearby item to wake them.
Danger Zone: Tapping the teacher, the blackboard, or non-disruptive students does not advance the level. Each part has exactly one problem student. The cat visible in some frames is a usable prop for creating a distraction, not just set decoration.
Mechanics: Level 18 is the first level where multiple characters are simultaneously visible but only one is the target. Players must scan the room for the most visually active or disruptive character to identify the correct interaction point each part.

Quick Tips for Brain Test 5 Level 18 (spoiler-free)

Look for the most visually active student in each part — the one who is moving, talking, or sleeping is always the target.
The cat that appears in some frames is interactive. Try dragging it toward arguing students as a distraction.
If you tap a student and nothing happens, that is not the problem student for that part. Scan for who else is active.

How to Solve Brain Test 5 Level 18 — Full Solution

Part 1 — "Help the teacher bring order to the classroom": drag the cat toward the arguing students at the front to distract them, or drag one disruptive student to a back seat away from the other.
Part 2 — A different student creates a new disruption. Identify the new prop that appeared and use it on the newly disruptive student.
Part 3 — A student has z-z's above their head indicating sleep. Tap them directly or use an available noise item near them to wake them up.
All disruptions are resolved. The teacher has order and the level ends.

Common Mistakes to Avoid

Tapping the teacher or blackboard in any part — neither is interactive for restoring order.
Using a Part 1 prop (the cat) in Part 2 when a new prop has already appeared — the new prop is always the answer for the current part.
