Build your 4-minute warm-up card
What are good concentration exercises before studying?
Short, slightly hard tasks that use the same kind of thinking as your subject: counting down by 7s before maths, spelling key terms backwards before reading, recalling the last lecture before memorizing. Do four, about a minute each, without your phone. Then start the first real task immediately, and plan two brief breaks into longer sessions.
Why the breaks? In a University of Illinois study published in Cognition (reported February 2011), 84 people did a repetitive 50-minute task. Most groups' performance slid over time; the group that switched to something else twice, briefly, held steady. Several of the warm-ups here come from a list of eight concentration exercises published by HAW Hamburg's student counselling office, such as recalling your day in reverse.
A warm-up is a start ramp, not a workout. Four minutes, then the real page.
When a warm-up isn't the answer
If you can't start because you don't know what to do first, a warm-up won't fix that: write the first tiny task on paper instead. If you're too tired to read a sentence, sleep beats every exercise here. And if starting has been hard in every class for months, talk to your school's student support team or a clinician; that's worth more than any card.
Use the card when you know what to study and just can't get going.

Paper warm-up vs game vs "just one scroll"
Statistics, the night before
8:58 PM Laptop open, problem set open, phone in hand "for one second". It's been eleven minutes.
9:10 PM Phone goes in a drawer. The card says: count down from 100 by 7s. They get to 51 and lose it; start again from 51.
9:14 PM Four warm-ups done. Question one is a standard deviation. They write the formula before reading the rest. It's 9:40 before they look up.
The card didn't make statistics easier. It made the first two minutes not-a-phone.
What these exercises can't promise
- There's no good evidence that any specific warm-up improves grades. These are start rituals, chosen because they're short, hard enough to need attention, and phone-free.
- SkillArena is a game. Its 1–100 ratings describe your performance in SkillArena's own games; they are not an IQ score or a medical, psychological or clinical assessment. Getting better at the games isn't proof your studying got better; our page on whether brain training games work goes into that.
- The break study used a lab task, not exam revision. We use it for one modest idea: plan two short switches into a long session.
