study tips for open book exams

An open book exam sounds easy, but it’s a trap.

Your professor knows you have the book. They aren't testing if you can memorize facts—they're testing if you can use them. The questions will force you to connect ideas and apply concepts, not just copy-paste a definition. Walking in thinking you can just look everything up is the fastest way to run out of time.

It's not about having a mountain of material. It's about having the right material, organized so you can find what you need in seconds.

Your Notes Are a Tool, Not a Crutch

The biggest mistake is leaning too hard on your materials. If you're flipping through the textbook for every single question, you're going to fail. Your notes are there for a quick reference, not for learning the topic for the first time during the test. You should know the stuff well enough to answer most questions from memory.

Think of it like a chef in a professional kitchen. They prep all their ingredients before service starts. They aren't running to the pantry for salt every time an order comes in. Your notes are your prepped ingredients.

I learned this the hard way in a sophomore year psych class. I walked in with my textbook, a binder overflowing with notes, and way too much confidence. Ten minutes in, I was frantically searching for some study mentioned in chapter 7. Or was it 8? I remember the professor looking at the clock—it was 2:37 PM—and I got that sinking feeling that I'd just wasted half the exam looking for things. I passed, but just barely.

Make a One-Page Cheat Sheet

Even if you can bring the whole textbook, make a one or two-page summary of the most important stuff. This is your go-to document.

It should have:

• Key formulas
• Important dates and names
• Core definitions
• Major theories

Look at this sheet first. Only dig into your big binder or the textbook if a question needs a really specific detail.

Organize for Speed

You have to find things instantly. Time spent searching is time you're not spending on your answer.

• Tab your textbook. Use sticky notes to mark every chapter and important sections. If you color-code them by topic, you can find things even faster.
• Make an index for your notes. A simple table of contents on the first page can turn a frantic search into a quick lookup.
• Write summaries in the margins. A quick sentence next to a key paragraph helps you get the point without re-reading the whole page.

Practice Under Pressure

The best way to prepare is to run a simulation. Find practice questions, set a timer, and try to answer them using only your organized notes. This immediately shows you where your system is weak. You'll figure out what's hard to find and which summaries don't make sense.

After a couple of practice runs, you'll walk into the real exam with a system you can trust.

How to Work During the Exam

Don't just start on question one and go in order.

1. Read all the questions first. Before you write anything.
2. Get the easy points. Answer everything you know off the top of your head. This builds momentum and banks you some points right away.
3. Tag the hard ones. Mark the questions you know will require digging through your notes and come back to them later.
4. Be concise. Professors want accurate, supported answers, not a novel. Adding fluff is just a way to waste time.

An open book exam isn't an excuse to be lazy. It’s a test of preparation, not memorization.
