ADHD and Exam Morning: Sleep, Breakfast and Anxiety

Two o'clock on the night before the exam. You are not in bed. You are trying to finish one more topic, and you know that even if you finish it, you will not remember it in the morning.

Or you are in bed but cannot sleep. The mind rehearses the morning: you read the question, you stare blankly, the time runs out.

This article is the last-night and exam-morning part of the series how to study for an exam with ADHD. I covered anxiety itself separately in the article ADHD and test anxiety; here I look at the last forty-eight hours of the calendar.

Last-night sleeplessness is really a cost

The answer to the question "what happens if I don't sleep for one night" is clearer than people think.

The review by Curcio and colleagues gathers the relationship between sleep loss and learning capacity and academic performance. There is a broad body of findings showing that insufficient, fragmented or poor-quality sleep goes along with daytime sleepiness, impaired attention and lower academic performance (Curcio et al., 2006).

The calculation here is simple. In the three hours you steal from sleep on the last night, at best you get through a topic at half efficiency. In return, throughout the exam your attention, your working memory and your reading speed run low. In ADHD these three are already narrow resources; piling a sleep debt on top of them comes at a high price.

So I suggest a single rule for the last night: no new topics. Only going over, one more time, things you have seen many times. Opening a topic you have never looked at at two in the night produces panic rather than knowledge.

Preparing for the possibility of not being able to sleep

In ADHD, sleep is already prone to shifting later, and the night of an exam magnifies this. In the article ADHD and sleep I described why going to bed at night gets so difficult.

Let us be realistic: the order to go to bed early on exam night often does not hold. But a few things can work.

Taking the sleep of two nights before the exam seriously. The chance of being unable to sleep on the last night out of excitement is high, and you cannot remove that chance completely. Sleeping properly the night before leaves you a little margin in case the last night goes badly. I cannot base this on a study; I am writing it as my own experience.

Writing down the finishing time in advance. "I'll go to bed when I'm done" is a dangerous sentence in ADHD, because the end is undefined. "At 23.00 I close it no matter what" is defined.

Not staying in bed when you cannot sleep. If you have not fallen asleep after forty minutes, get up, do something boring in dim light and go back when sleep comes. Tossing in bed with anxiety pairs the bed with anxiety.

Setting the morning alarm in two layers. An alarm at the other end of the room and a second alarm on the phone. Sleep inertia is especially risky on exam morning.

The relationship of anxiety to grades

Brushing off test anxiety with "don't exaggerate, it will pass" is not right. Its effect has been measured.

A meta-analysis that brought together thirty years of research found, in the data of 238 studies, that test anxiety was negatively related to a wide range of achievement measures, from standardized tests to university entrance exams and grade point average. In the same analysis self-esteem emerged as one of the strong predictors of test anxiety; the perceived difficulty of the exam and the weight of its consequences were also linked with anxiety (von der Embse et al., 2018).

The self-esteem finding is meaningful on the ADHD side in particular. The expectation "I'll forget again, I won't be able to make it again," accumulated over school years that passed without a diagnosis, walks into the exam hall before the subject of the day does. There is a close concept in the glossary: anticipatory anxiety.

Avoidance and last-minute panic

The most visible result of anxiety is being unable to study.

When you open the topic you will see how far behind you are. Not seeing is more comfortable. So with three days left to the exam the desk gets tidied, the phone gets cleaned, a new program gets written. I described the mechanism of this freezing in the article on task paralysis.

Then the last day comes and panic kicks in. Urgency suddenly supplies the starting force that could not be found for months, and you can really study. I call this panic productivity, and the most deceptive thing about it is that it works.

It works, but at a cost. The same urgency carries on in the exam hall the next morning, and there it does not speed you up, it locks you. In an exam entered with arousal that has been rising all night, attention goes into a narrow tunnel.

This cycle cannot be broken on the last night. Where it can be broken is two weeks before the exam, where you split the job into small pieces and measure each piece. In the article on deadlines I wrote about ways of making a big date visible.

Exam morning

Turning the morning into an order written in advance is one of the things that works best in ADHD. You do not have to make decisions in the morning.

A bag prepared the night before. ID, pen, eraser, water, a sweet if you need it. An ID being searched for in the morning sets the tone of the whole day.

A fixed breakfast. Exam morning is not the place to try something new. A breakfast you are used to, that does not upset your stomach and that contains protein. Not eating at all is not a good idea either; hunger makes it harder to tell the symptoms of anxiety from anxiety.

Keeping caffeine at your normal level. For someone who never drinks coffee, drinking two on exam morning can noticeably increase test anxiety. If you drink one coffee every day, drink one coffee.

Leaving early and arriving early. The chance of being late is the most easily preventable source of anxiety. In the time that remains after you arrive, do not try to review topics; walk, drink water, sit.

No book in the last twenty minutes. A topic you do not know that catches your eye in a book opened right before the exam does not teach you that topic, it only increases the panic.

The first three minutes When the booklet is opened, do not jump straight to the first question. Set aside three minutes. Empty the formulas, dates and keywords you are holding in your mind into a corner of the paper. Then skim the questions quickly and put a small mark next to the ones you know. This gives you a place to return to when the moment comes that your mind goes blank.

Reading arousal in the body differently

The heart speeds up, the hands sweat, the stomach knots. These are not anxiety itself; they are the body preparing for action. The same symptoms occur in an exciting race too.

Jamieson and colleagues told some of the participants preparing for a graduate admission exam that arousal before the exam can help performance. The group that received this information did better than the control group on the math section of a practice exam; the real exam scores they reported later were also higher than the controls' on the math section (Jamieson et al., 2010).

This study was not done on a sample with ADHD and is not a solution on its own. But trying it costs nothing. Saying "my heart is fast because my body cares about this" instead of "calm down" at least tires you less.

The week before the exam

What can be done for the last night and the morning is limited. The real work begins a week earlier, and in ADHD the biggest enemy of this week is that the exam still stands in the "not now" zone.

A routine worth trying could look like this.

Seven days out: a map of what is missing. Write the topics as headings on a single sheet, not all of them, only the headings. Next to each heading put one of three marks: I know it, I half know it, I don't know it at all. This sheet makes the anxiety concrete. The feeling "I know nothing" usually turns into the fact "I don't know these three headings," and three headings are far less frightening than everything.

Between six and three days out: the half-known. In this period, trying to learn what you do not know at all is generally a bad investment. The highest return is in closing the topics you half know. At the end of each session close the book and ask yourself a few questions on that day's topic; let what you could not answer be the first job of the next day.

Two days out: the last mock exam. In real conditions, with the real time, without the phone. Its aim is not the score but to live through the exam scene once more. Afterward only analyze the wrong answers, do not go into a new topic.

One day out: logistics day. If possible, see the exam place in advance. Prepare the bag, plan the travel, set the alarm. As for the subject, only light review.

The hardest side of this week is that the number of days left is not felt. Writing the exam date, with the number of days left, in a place you see every day is simple but it works. Making time visible is the cheapest counter-move to the problem I described in the article on time blindness.

After the exam

The moment you hand in the paper, your mind starts counting the questions you lost, and this counting often turns into an indictment.

Instead of that indictment, it is possible to write two questions. On which question did I lock up, and what happened at that moment? What could I do differently at that moment next time? The answers usually turn out small: I did not skip the question, I did not look at the time markers, I did not sleep the night before. Small answers can be changed.

I also want to say this. Not being able to show what you know in an exam does not mean you do not know it. Confusing these two is the earliest and most wrong decision many people with ADHD make about themselves. What was measured in that minute was less your knowledge than where your attention was, and where your attention is can really be worked on.

If anxiety also narrows your life outside the exam, disturbs your sleep and eating routine, or comes with the same intensity before every exam, you do not have to try to solve it alone. Talking with a specialist can be more effective than all the tips on this list.
