How to Study for an Exam When You Keep Getting Distracted

Imagine it is 11 p.m. the night before an exam. You have opened the same chapter four times, and each time you have ended up on your phone within a few minutes. You are not lazy. You are studying in a setup that makes distraction almost free.

That is the first thing to fix. Distraction during revision is usually a problem with the environment and the size of the task, not a personal failing. Below are the fixes that actually change behaviour, in the order worth trying them.

Start with the smallest possible version of the task

A vague task like “revise biology” gives your brain nothing to hold on to, so it drifts. A specific one gives it a finish line.

Before each study block, write one sentence: “In the next 25 minutes I will ______.” For example:

• Redo questions 1–6 from the 2023 past paper.
• Write out the four stages of the process from memory, then check them.
• Summarise pages 40–44 in five bullet points.

Aberystwyth University's exam advice recommends looking over past papers because they show what could come up and help you focus on what actually needs revising. That also turns “revise everything” into a list of concrete questions you can answer.

If you freeze before you even start, the problem may be task paralysis rather than distraction; this guide to getting unstuck covers that separately.

Make distraction expensive: the phone setup

The University of the Cumberlands' finals-week advice is blunt about phones: if you struggle with distractions, turn the phone off, give it to a friend while you study, or put it on the other side of the room.

Pick the level that matches how bad the problem is:

1. Mild: phone face down, notifications off, on the far corner of the desk.
2. Moderate: phone in a drawer in another room, timer running on your laptop instead.
3. Severe: phone handed to a housemate or left in a bag by the front door until the block ends.

Face down is not enough for many people, because the phone still pulls attention even when it is not lighting up. If that sounds familiar, read why a face-down phone still distracts you.

Use short sprints instead of open-ended sessions

A common workplace suggestion is to start with just 25 minutes of uninterrupted work, then take a short break. That structure works for revision too, because it gives you an end point you can tolerate.

A simple exam-season block:

• 25 minutes on one specific task, phone away.
• 5 minutes away from the desk: water, stretch, window.
• Repeat three or four times, then take a longer break.

Aberystwyth's advice points the same way: you tend to learn better in chunks rather than cramming everything into one sitting, so break revision up at regular intervals, such as every half an hour. If 25 minutes feels too long at first, start with 15 and add five minutes each day.

Why 25 and not 50? There is a longer history behind that number in why the Pomodoro Technique is 25 minutes.

Protect the block: what to do about interruptions you cannot remove

Some interruptions are not yours to control: a flatmate, a delivery, a group chat about the exam. The cost is bigger than it feels. Research cited by Fast Company, drawing on the American Psychological Association, indicates that switching between tasks can cost up to 40% of productive time. Gloria Mark's work, reported in the same article, found that after a distraction it can take an average of 23 minutes and 15 seconds to return to full focus on the original task.

That number is an average from workplace research, not a rule about your revision, but the direction is clear: preventing an interruption is cheaper than recovering from one. Practical moves:

• Tell people your study window in advance: “I'm revising 7–7:50, can we talk after?”
• Put a note on your door with the end time, not just “do not disturb”.
• Batch replies: check messages only in your breaks, not during blocks.

Study with someone, but choose carefully

The University of the Cumberlands suggests studying with a classmate for a deeper understanding of the content, with one condition: choose someone who will help you focus, not someone you will be too easily distracted by.

A workable format is a silent co-study session: same room or video call, cameras on, microphones off, 25 minutes of work, then compare answers to three past-paper questions. The comparison is where the learning happens; the shared quiet is what keeps you at the desk.

Space it out, and plan the week before the panic

Cramming the night before is the setup most likely to fail, because fatigue and distraction arrive together. The Cumberlands advice is direct: it is easier to remember content studied in shorter intervals over several days than all at once.

A realistic five-day plan for one subject:

• Day 1: read and summarise one topic; make ten flashcards.
• Day 2: test yourself on those flashcards, then start the next topic.
• Day 3: past-paper questions on topics 1–2, timed.
• Day 4: new topic plus a mixed set of questions from everything so far.
• Day 5: full past paper under exam conditions, then review only what you got wrong.

University library guidance also recommends blocking dedicated study periods in your calendar and giving more time to difficult courses and higher-credit classes, with a rough rule of thumb of one to three hours per week per course. Treat that as a starting point, not a target you must hit perfectly.

When a fix stops working

Attention is not fixed. A study on visual attention published in the journal Neuroscience & Biobehavioral Reviews described habituation: when a distracting stimulus keeps appearing, the response to it tends to decrease, and if the stimulus is withheld for a while, the response can recover. In plain terms, a familiar distraction can fade during a session but come back after a break, and a change of scene can reset your tolerance.

So if your usual setup stops working:

• Change location: library, kitchen table, a different chair.
• Shorten the block from 25 to 15 minutes for a day.
• Switch from reading to active recall: cover the page and write what you remember.
• Take a real break away from screens, not a scroll.

If you have tried these for a couple of weeks and distraction is still constant, or it comes with persistent anxiety or exhaustion, talk to your tutor or a health professional. That is not a study-technique problem, and it is not something to push through alone.

Your next step

Tonight, before you open a book, do three things: write one specific task for a 25-minute block, put your phone in another room, and set a timer. One block is enough to start. If you want the timer to also give you something to look at when it ends, PomoGrove is a free focus timer where completed sessions grow collectible caterpillars into butterflies.
