How to study 100 pages in one week

So you've got an exam in a week and about 100 pages of lecture slides you haven't really looked at yet. I've been here more times than I want to admit, and the first thing I want to say is that a week is enough. I'm not saying that to make you feel better. You can do it.

But only if you stop doing the thing everybody does, which is opening the slides on Monday and reading them front to back, then doing it again on Wednesday, then panicking on Saturday because none of it stuck.

Why re-reading feels like studying but isn't

Here's the trap. When you read something for the second time it feels familiar. Your brain goes "yeah, I know this", and that feels nice, so you keep going.

The problem is that recognising something isn't the same as being able to write it down yourself. In the exam nobody shows you the slide and asks if it looks familiar. They ask you to explain osmosis on a blank page. Those are two different skills, and re-reading only trains one of them.

The test is easy. Close the slides right now and say out loud what the last section was about. If you can't, you didn't learn it. You just looked at it.

The plan

Day 1: cut it into pieces and be honest

Don't study yet. Go through all 100 pages quickly, maybe 45 minutes, and split them into chunks of about 10 pages that belong together. Give each chunk a name.

Then mark each one: know it, sort of, no idea. Be honest here, because this is the whole point. Most people find that out of 100 pages, maybe 30 are really new. That's a much smaller problem than the one you thought you had this morning.

Days 2 to 4: first pass, but actively

Take three or four chunks a day, starting with the "no idea" ones while you still have the energy for them.

For each chunk:

1. Read it once. Once, not three times.
2. Close it.
3. Write down everything you remember on a blank page. Messy is fine.
4. Open it again and see what you missed.

Step 3 is the whole thing. It's going to feel bad the first few times, because you'll remember way less than you expected. That feeling is the method working, not you failing. The gap you just found is exactly what you need to study, and you'd never have found it by reading.

Day 5: turn it into questions

Now go back over everything and turn it into questions instead of statements.

Not "osmosis is the diffusion of water across a membrane" but "what is osmosis, and which way does the water move?" Questions make you dig the answer out. Statements just let you nod along.

If you're making flashcards, make them now, not on day 1. You'll write much better ones once you know which bits actually confuse you.

Day 6: explain it to someone

Best day of the week and the one everyone skips.

Take each chunk and explain it out loud like you're talking to someone who doesn't do your subject. A friend, your flatmate, your mirror, whatever. The moment you get stuck halfway through a sentence, you've found something you don't actually understand. You thought you did, because you'd read it four times.

It's uncomfortable and it works better than anything else on this list.

Day 7: only the bits you got wrong

Don't review everything. Go through your notes from the week and find the things you kept missing. There'll be fewer than you're afraid of, maybe ten or fifteen things.

Then sleep properly. A tired brain is bad at digging things out, and digging things out is the whole exam.

A few things that actually matter

Spread it out. Twenty minutes on the same chunk on three different days beats one hour in a single sitting. Forgetting a bit and then dragging it back is what makes it stick. It feels less efficient, which is why nobody does it.

Do the hard chunks first, every day. By the evening you'll only want to review the stuff you already know, because that feels nice. That's exactly the stuff you don't need.

Write by hand for the recall bit. It's slower, and slower is the point here.

Stop highlighting. Highlighting is re-reading with a pen in your hand. If the page ends up mostly yellow, all you've decided is that everything is important, which is the same as deciding nothing.

If a week turns into three days

It happens. Cut the plan down instead of giving up on it:

• Day 1: chunk it, then recall-test the "no idea" ones only
• Day 2: questions, then explain the worst three chunks out loud
• Day 3: only your mistakes, then sleep

You won't know everything. But you'll know the things you kept getting wrong, which is where most of the marks are anyway.

The short version

Reading isn't studying. Closing the book and trying to get the answer out of your head is studying. Everything above is just a schedule for doing more of the second thing and less of the first.

A week is enough. Three days you can survive. Tonight isn't, so start now.
