How to Prepare for an Exam in One Day

One day is not enough to learn a whole course, and nobody can promise otherwise. It is enough to secure the marks that are easiest to win. This plan spends every hour on those.

The short answer

  1. Spend the first 30 minutes finding the topics worth most marks, from past papers or the syllabus.
  2. Study those first, in 40-minute blocks, testing yourself at the end of each block.
  3. Do one past paper, or past questions, under time in the afternoon, and fix what you got wrong.
  4. Skip what is rare and hard; one well-understood common topic is worth more than three half-read ones.
  5. Stop by evening, review once, and sleep: memory settles while you sleep.

The first 30 minutes: decide what is worth studying

Open the last two or three past papers, or the syllabus, and list the topics that come up most and carry the most marks. Circle the five to eight you will cover today, starting with the ones you half know already: they turn into marks fastest.

The day, hour by hour

WhenWhat to do
Morning, block 1 to 3One topic per 40-minute block: read the summary, then close it and write what you remember, then check. Five minutes' break between blocks.
MiddayA real break and a meal. Ten minutes outside helps you focus again.
Afternoon, block 4 to 5Two more topics the same way.
Late afternoonOne past paper or a set of past questions, under time. Mark it.
Early eveningRedo only the questions you got wrong. Write the corrections on one page.
NightRead that one page once, set out what you need for the exam, and sleep.

Test yourself fast

With one day, re-reading is a luxury you cannot afford. After every block, spend the last ten minutes answering questions with the notes closed:

  • Write the three main points from memory, then check what you missed.
  • Turn headings into questions ("What causes...?", "How do you calculate...?") and answer them aloud.
  • Make a few flashcards for formulas and definitions you must have word for word.

What to skip, and what not to

  • Skip topics that are rare in past papers and new to you.
  • Skip rewriting or colouring your notes; it feels useful and costs hours.
  • Do not skip the past paper: it shows how questions are worded and where marks are given.
  • Do not skip sleep. Staying up all night lowers what you can recall the next day more than one more topic adds.

Your one-day exam plan

  1. First 30 minutes: list the five to eight topics worth most marks.
  2. Morning: one topic per 40-minute block, notes closed for the last ten minutes.
  3. Midday: a real break.
  4. Afternoon: two more topics, then one timed past paper.
  5. Evening: redo the questions you got wrong; one page of corrections.
  6. Night: read that page once, prepare your things, sleep.

Frequently asked questions

Can I pass an exam by studying one day before?

You can secure the most common, highest-mark topics if you choose them from past papers and test yourself on them. Covering the whole course in a day is not realistic.

Should I stay up all night before an exam?

No. Sleep is when what you studied settles into memory. An all-nighter usually costs more than the extra hours give.

What should I study first when I have little time?

The topics that appear most often in past papers and that you already half know. They turn into marks fastest.

Make your notes into questions

Add your notes, slides or a PDF to the LoWisa Study Kit and it builds quizzes and flashcards from them, so every block ends with a test.
