That happened a lot when I made attempts on Brainiac. I forgot the magnet a couple times, which costed the run, had 4/5 exam questions answered. Viktor changing his jacket so fast forced me to use so many lemon-berries. I sometimes dodge runs if too many notebooks spawn in the middle 6 rooms, just for a greater chance at getting a good exam location.
Keep at it. You can do this!
Funny thing is I didn't get any of the 4 normal questions on all 10 notebooks wrong, I listened to Albert the whole time even on the 6-10th notebook to minimize Viktor's speed and using the warp doors and searching the farther corridors while Viktor is on the other side of the school to buy me more time, but when the final chase commenced, he was as fast as if he saw me with the knife/Albert parts which he never did! He is also impossible to juke in any corridor in the final chase without an anti-Viktor item! His speed is 4 times faster than on boi and default difficulty!
