Common School and Study English Phrases: Keep Up With, Turn In an Assignment, and Learn by Doing
School and study life have their own vocabulary, and much of it comes in short, fixed phrases rather than single words. When you read about classrooms, homework, and exam preparation in English, you keep meeting the same expressions. They appear in TOEIC conversations between coworkers and students, in TOEFL and IELTS reading passages about education, and in SAT-style texts about learning.
The five phrases below describe the daily rhythm of study: staying on track, handing in work, getting ready for tests, learning through practice, and being judged on results. Knowing them well does more than build vocabulary. It helps you understand the tone of a passage, because each phrase signals whether a text is talking about effort, deadlines, or judgment. When you can read these phrases automatically, you free up attention for the harder ideas around them.
Keep Up With
Literal Meaning
Word by word, "keep up with" suggests holding your position upward while staying together with something. It pictures a person matching the speed of a moving group.
Actual Meaning
"Keep up with" means to stay at the same level or speed as something that is moving forward, so that you do not fall behind. In study contexts, it means following the pace of a class, a course, or a reading schedule.
Origin or Background
The phrase comes from the simple image of walking or running beside others without slowing down. It moved into study language because courses progress steadily, and a student who matches that pace is described as "keeping up with" the class.
Common Contexts
You will see "keep up with" in study advice, teacher comments, and casual conversation. It is neutral in register and works in both speech and writing, from friendly chats to fairly formal reports.
Example
"Because the course covered a new grammar topic every week, the student made a habit of reviewing each night just to keep up with the lessons."
What It Means
The sentence shows a student responding to a fast course. Nightly review was the effort needed to match the weekly pace so that no topic was left unlearned.
Common Mistake
Learners often forget the word "with" before an object. You "keep up with the class," not "keep up the class." Without "with," the phrase changes meaning to maintaining something.
Turn In an Assignment
Literal Meaning
Word by word, "turn in" suggests rotating something toward the inside of a place. Combined with "an assignment," it literally pictures moving a piece of work inward, toward a person or office.
Actual Meaning
"Turn in an assignment" means to give completed work to a teacher or an online system by a deadline. The phrase focuses on the act of submitting, not on doing the work itself.
Origin or Background
"Turn in" has long meant to hand over or deliver something, and the phrase is common in American English. It became a standard study expression because schools collect homework, essays, and projects on set dates.
Common Contexts
You will hear "turn in an assignment" in classrooms, in messages about deadlines, and in school instructions. It is fairly informal but completely acceptable in school settings; very formal writing may prefer "submit."
Example
"The student finished the essay early and decided to turn in the assignment a day before the deadline so there would be no last-minute stress."
What It Means
The sentence describes good planning. By submitting the essay ahead of time, the student avoided rushing and removed the pressure of a tight deadline.
Common Mistake
Learners sometimes say "turn in for an assignment" or "hand in to the teacher the assignment" with awkward word order. The natural patterns are "turn in an assignment" or "turn the assignment in."
Prepare for an Exam
Literal Meaning
Word by word, "prepare" means to get ready, and "for an exam" shows the purpose. Literally the phrase means to make yourself ready ahead of a test.
Actual Meaning
"Prepare for an exam" means to study and practice in advance so that you can perform well on a test. It covers reviewing notes, doing practice questions, and managing time before the exam day.
Origin or Background
This phrase is compositional, so it has no special backstory. The verb "prepare" naturally pairs with the preposition "for" to show purpose. It became a fixed study expression simply because exams are a regular and important event in education.
Common Contexts
You will see "prepare for an exam" in study guides, school announcements, and conversations among students. It is neutral and suits both informal speech and formal writing.
Example
"To prepare for the exam, the student spread the work across three weeks, studying one section each day instead of trying to learn everything in a single night."
What It Means
The sentence shows a sensible study plan. By dividing the material over time, the student avoided cramming and built steady, lasting understanding.
Common Mistake
Learners often use the wrong preposition and say "prepare to an exam" or "prepare the exam." Use "prepare for an exam." "Prepare an exam" would mean creating the test, which is a teacher's job.
Learn by Doing
Literal Meaning
Word by word, "learn by doing" means to gain knowledge through the method of doing something. The small word "by" shows the way the learning happens.
Actual Meaning
"Learn by doing" means to gain skill and understanding through real practice and action, rather than only through listening or reading. It describes an active approach to learning.
Origin or Background
The phrase is transparent and has been common in education writing for a long time. It captures a widely shared idea that practice builds understanding, and it often appears in discussions of practical training and skill courses.
Common Contexts
You will see "learn by doing" in articles about teaching methods, training programs, and skill development. It carries a positive tone and fits both informal and formal contexts.
Example
"The cooking class followed a simple idea: students learn by doing, so every lesson ended with each person preparing the dish from start to finish."
What It Means
The sentence describes a class built on practice. Instead of only watching, students cooked the dish themselves, gaining skill through direct action.
Common Mistake
Learners sometimes write "learn by do" or "learn with doing." Keep the "-ing" form after "by," since "by" needs a gerund here, and avoid swapping in "with."
Academic Performance
Literal Meaning
Word by word, "academic" relates to study and education, and "performance" means how well something is done. Literally the phrase means how well a person performs in study.
Actual Meaning
"Academic performance" means the level of success a student shows in their studies, often measured by grades, test scores, and completed work. It is a general term for results in school.
Origin or Background
This phrase is compositional and formal. "Performance" has long meant the quality of how a task is carried out, and pairing it with "academic" narrowed it to the world of study. It is standard in reports, research, and school documents.
Common Contexts
You will see "academic performance" in school reports, research articles, and formal discussions of education. It is formal in register and more common in writing than in casual speech.
Example
"The school noticed that students who slept enough hours showed stronger academic performance, especially on tasks that required careful concentration."
What It Means
The sentence reports a pattern the school observed. Students who rested well tended to get better study results, particularly on work that needed deep focus.
Common Mistake
Learners sometimes say "academic performances" when speaking generally, but the term is usually uncountable in this sense. Also avoid "study performance," which is far less natural than "academic performance."
Conclusion
These five phrases - keep up with, turn in an assignment, prepare for an exam, learn by doing, and academic performance - describe the everyday cycle of effort, deadlines, practice, and results that fills school and study texts. Because exam passages and conversations return to these ideas constantly, recognizing each phrase instantly will sharpen your reading and listening. As you study English, watch for these expressions in articles and dialogues, and notice exactly which part of study life each one points to. With practice, they will feel as clear and quick to read as ordinary words.
