ACCUPLACER Writing: Sentence Skills and Revising Text
Students preparing for college placement tests sometimes focus heavily on mathematics and reading while leaving writing skills until the last minute. Reviewing grammar and sentence construction can help you approach writing-related questions more confidently. ACCUPLACER test content and available sections can vary by assessment. Check the official College Board information and your institution's instructions to determine which tests you need to take.
1. Recognize complete sentences
A complete sentence generally expresses a complete thought and contains an independent clause. An independent clause has a subject and a verb and can stand on its own. For example: - Complete: The student reviewed the chapter before class. - Fragment: Because the student reviewed the chapter before class. The second example introduces a dependent clause but does not complete the thought. It needs additional information, such as: “Because the student reviewed the chapter before class, the lecture was easier to follow.” When revising a sentence, identify its subject and main verb first. Then check whether the thought is complete.
2. Avoid run-on sentences
A run-on sentence occurs when independent clauses are joined incorrectly. For example: The lecture ended the students went to the library. The sentence can be corrected in several ways: - The lecture ended, and the students went to the library. - The lecture ended; the students went to the library. - After the lecture ended, the students went to the library. Choose a correction that preserves the intended meaning and creates a clear relationship between the ideas.
3. Check subject-verb agreement
The subject and verb should agree in number. - Correct: The student studies every evening. - Correct: The students study every evening. Be careful when extra words appear between the subject and verb. In “The list of assignments is on the desk,” the subject is list, not assignments. The verb therefore takes the singular form.
4. Use punctuation to clarify meaning
Commas can separate introductory phrases, items in a series, and certain clauses. Semicolons can join closely related independent clauses. Apostrophes show possession or form contractions. Punctuation should make a sentence easier to understand, not simply make it look more complicated. For example: Before the exam began, the students put away their notes. The comma separates the introductory phrase from the main clause. When revising, check whether punctuation reflects the sentence's structure. Do not add a comma simply because you would pause while reading aloud.
5. Revise for clarity and concision
Good writing communicates an idea directly. Remove unnecessary repetition and replace vague expressions with specific language when the context supports it. For example: The reason why the student was late was because the bus arrived late. A clearer version is: The student was late because the bus arrived late. When answering revision questions, compare the options carefully. The best choice should improve the sentence without changing its intended meaning or introducing a grammatical error.
6. Build a short daily practice routine
Spend 15–20 minutes reviewing one skill at a time. Practise sentence fragments on one day, subject-verb agreement on another, and punctuation later in the week. Keep a record of recurring errors and revisit them periodically. Use official ACCUPLACER preparation materials to understand the test format, and confirm which writing or language skills your placement assessment covers.
Final thoughts
Writing skills improve when you can explain why a sentence works. Practise identifying clauses, correcting agreement errors, using punctuation accurately, and removing unnecessary words. Consistent, focused revision is more effective than memorizing grammar rules without applying them.
