Studying is not always about sitting quietly with a book. Sometimes you hit the books, sometimes you burn the midnight oil, and sometimes you feel like your brain has completely gone blank before an exam.
English has many colorful idioms that describe these situations in a natural and memorable way.
Idioms are expressions whose meaning is different from the literal meaning of their individual words.
For example, if someone says, “I need to hit the books,” they do not mean they are going to punch their textbooks. They simply mean they need to study.
Learning idioms about studying can make your English sound more natural in conversations, essays, and exams. Imagine a student named Sara preparing for her final test.
She tells her friend, “I’ve been burning the midnight oil all week, but I still need to brush up on math.” Her friend laughs and replies, “Take a break before you burn yourself out!”
That short conversation uses several common English idioms—and that is exactly how native speakers use them.
📚 Fun Fact About Study Idioms
Many English idioms about studying come from everyday activities. “Hit the books” became popular as a playful way of saying “study hard,” while “burn the midnight oil” comes from the time when people used oil lamps to work or study late at night.
40+ Idioms About Studying You Should Know
1. Hit the Books
Meaning: To start studying seriously.
“I have an exam tomorrow, so I’d better hit the books tonight.”
This is one of the most common informal study idioms in American and British English.
Quick tip: Use it with friends and classmates. It is not usually suitable for a formal academic essay.
2. Burn the Midnight Oil
Meaning: To work or study late into the night.
“I was burning the midnight oil to finish my research paper.”
The image is old-fashioned, but the idiom is still widely understood.
Cultural note: Before electricity, people used oil lamps to work after dark. So the phrase literally refers to using lamp oil late at night.
3. Crack a Book
Meaning: To open a book and begin studying.
“I haven’t cracked a book all weekend, and my exam is Monday!”
This is often used humorously when someone has been avoiding their studies.
4. Hit the Books Hard
This stronger variation suggests serious or intense studying.
“She hit the books hard before her final exams.”
It works well in casual conversations when talking about exam preparation.
5. Brush Up On Something
Meaning: To review something you learned before.
“I need to brush up on my grammar before the IELTS test.”
This idiom is extremely useful for language learners because you can use it for grammar, vocabulary, mathematics, history, or almost any subject.
6. Learn by Heart
Meaning: To memorize something completely.
“We had to learn the poem by heart.”
It is especially common when talking about poems, speeches, formulas, songs, or important facts.
Don’t confuse it with: know by heart.
“I know this poem by heart” means you already remember it perfectly.
7. Know Something Like the Back of Your Hand
Meaning: To know something extremely well.
“After studying the map for months, he knows the city like the back of his hand.”
You can use this beyond studying too.
8. Get Your Head Around Something
Meaning: To understand something difficult.
“It took me a while to get my head around this algebra problem.”
This is particularly common in British English.
Mini dialogue
Ali: “Do you understand this chapter?”
Hamza: “Not really. I’m still trying to get my head around it.”
Ali: “Let’s study it together.”
9. Put Your Thinking Cap On
Meaning: To start thinking carefully about a problem.
“Put your thinking cap on and try to solve this puzzle.”
This expression is often playful and is especially common when speaking to children or students.
10. Rack Your Brain
Meaning: To think very hard to remember or solve something.
“I racked my brain trying to remember the answer.”
Usage note: You may also hear “rack your brains.” Both forms are used.

These expressions are great for casual conversations and social media, but avoid overly playful language in formal academic writing.
🌍 Idioms Used by Native Speakers in Real Life
Here is how a natural conversation might sound:
Emma: “Are you ready for the exam?”
Jack: “Not even close. I’ve been snowed under with assignments.”
Emma: “You should hit the books tonight.”
Jack: “I know. I might have to pull an all-nighter.”
Emma: “Don’t burn yourself out. Take breaks.”
Jack: “You’re right. I’ll give it my best shot.”
Notice how native speakers do not usually use ten idioms in every sentence. They mix idioms with ordinary language.
That is the key: natural English is about using idioms at the right moment, not using as many as possible.
📊 Emotional Scale: From Mild Study Stress to Extreme Pressure
| Level | Useful expressions |
|---|---|
| 🟢 Mild | A little confused, brushing up on something |
| 🟢 Moderate | Have a lot on your plate, feel under pressure |
| 🟡 Strong | Snowed under, swamped, rack your brain |
| 🟠 Very strong | At your wits’ end, go blank |
| 🔴 Extreme effort | Pull an all-nighter, burn the midnight oil |
This scale helps learners choose an expression that matches the situation.
✍️ How to Use Study Idioms in Daily Life
In speaking
Use informal expressions when chatting with classmates or friends:
“I need to hit the books tonight.”
“I’m snowed under with homework.”
In writing
Idioms can make personal writing more natural, but do not overuse them.
Instead of:
“I studied very late.”
You could write:
“I burned the midnight oil preparing for my final exam.”
In professional English
Choose expressions that fit the workplace:
- stay on top of
- get up to speed
- bring someone up to speed
- go the extra mile
- keep up with
For formal reports, however, simple and precise language is often better.
⚠️ Common Mistakes English Learners Make
1. Using an idiom literally
❌ “I hit my books because I was angry.”
✅ “I hit the books because I had an exam.”
2. Changing the idiom
❌ “I burned the midnight candle.”
✅ “I burned the midnight oil.”
3. Using too many idioms
A sentence packed with idioms can sound unnatural.
❌ “I hit the books, burned the midnight oil, racked my brain, and went the extra mile every five minutes.”
Use one or two where they fit naturally.
4. Using informal idioms in formal writing
Expressions such as “hit the books” are conversational. In an academic essay, “study intensively” may be more appropriate.
5. Confusing “learn by heart” with understanding
If you learn something by heart, you memorize it. That does not necessarily mean you understand it.
