Choose the sentence with the correctly placed comma after an introductory phrase.
After the rain, stopped we went outside.
After the rain stopped, we went outside.

Which is the correct contraction for 'do not'?
dont
dosn't
don't
do'nt
The apostrophe replaces the missing letter 'o' in 'not', forming 'don't'. Proper placement of the apostrophe is essential for standard contractions. Incorrect forms either omit or misplace the apostrophe. For more on apostrophes, visit .
Which sentence ends with the appropriate punctuation for a question?
You're coming with us?
Youre coming with us?
You're coming with us.
You're coming with us.
Questions should end with a question mark rather than a period. The second sentence correctly uses a question mark after 'us'. The third option also uses a question mark but omits the apostrophe in 'You're', making it incorrect. See for more.
Which sentence uses an exclamation mark correctly?
Watch out?
Watch out.
Watch out!
Watch out
An exclamation mark conveys strong emotion or warning. The second option places it correctly after 'Watch out'. The other options either lack it or use different punctuation marks. More examples can be found at .
Which sentence correctly uses a colon?

There are: three things I love pizza, tacos and ice cream.
There are three things I love: pizza, tacos, and ice cream.
There are three things: I love pizza, tacos, and ice cream.
A colon introduces a list when the preceding clause is complete. The second sentence correctly places the colon after 'love' and before listing the items. Incorrect options either omit the colon or place it in the wrong position. See .
Select the correctly punctuated sentence with its vs. it's.
Its's going to rain today.
Its going to rain today.
It's going to rain today.
Its' going to rain today.
'It's' is the contraction for 'it is' and requires an apostrophe before the 's'. 'Its' without an apostrophe indicates possession. The second option correctly uses the contraction form. Learn more at .
Which sentence correctly uses a hyphen?
He is a well-known-author.
He is a well known-author.
He is a well known author.
He is a well-known author.
Compound adjectives before a noun should be hyphenated to link the words. The second sentence properly uses a hyphen between 'well' and 'known'. The other options either omit the hyphen or place it incorrectly. For details, visit .
Which sentence correctly uses a semicolon to join two related independent clauses?
I love to read; and I visit the library often.
I love to read; I visit the library often.
I love to read, I visit the library often.
I love to read; because I visit the library often.
A semicolon joins two independent clauses without a conjunction. The third sentence correctly uses a semicolon to link the related ideas. Using a comma here would create a comma splice. More examples at .
When is it most appropriate to use a colon?
To offset a nonrestrictive clause.
To introduce a list.
To indicate a pause stronger than a period.
To join two independent clauses without a conjunction.
A colon is typically used to introduce a list, quotation, or explanation after an independent clause. It should not be used simply to indicate a pause or to join clauses without context. For guidance, see .
Which sentence correctly uses em dashes to add emphasis?
The secret ingredient - chocolate, makes it delicious.
The secret ingredient chocolate makes it delicious.
The secret ingredient - chocolate - makes it delicious.
The secret ingredient - chocolate - makes it delicious.
Em dashes - longer than hyphens - are used to set off parenthetical or emphatic elements. The second sentence uses them correctly around 'chocolate'. Using hyphens or commas in place of em dashes is incorrect here. Learn more at .
Which sentence correctly uses an ellipsis?
She hesitated.... then spoke.
She hesitated then... spoke.
She hesitated.. then spoke.
She hesitated... then spoke.
An ellipsis consists of three dots and indicates omitted text or a trailing off. The first sentence correctly uses three dots with no extra spaces at the start. The other options have too few or too many dots, or awkward placement. See .
Which sentence correctly uses the possessive form of the plural noun 'children'?
The children's toys were everywhere.
The childrens's toys were everywhere.
The childrens toys were everywhere.
The childrens' toys were everywhere.
The plural noun 'children' becomes possessive by adding an apostrophe plus 's', forming 'children's'. The second sentence correctly shows ownership. Other forms either misplace or omit the apostrophe. More on apostrophes at .
Which example contains a comma splice?
I wanted to go, but it was raining.
I wanted to go, it was raining.
I wanted to go; it was raining.
I wanted to go but it was raining.
A comma splice occurs when two independent clauses are joined by only a comma. The second option improperly uses a comma without a coordinating conjunction. Semicolons or conjunctions are needed instead. For details, visit .
Choose the sentence that correctly uses commas to set off a nonrestrictive clause.
My brother who lives in New York is visiting.
My brother who lives, in New York, is visiting.
My brother, who lives in New York, is visiting.
My brother, who lives in New York is visiting.
Nonrestrictive clauses add extra information and should be set off by commas. The first sentence correctly encloses 'who lives in New York' in commas. Omitting or misplacing commas changes the meaning or breaks punctuation rules. See .
Which sentence correctly uses an en dash to indicate a range?
The score was 3-2 in the final match.
The score was 3 - 2 in the final match.
The score was 3 - 2 in the final match.
The score was 3 - 2 in the final match.
An en dash without spaces indicates a numeric range. The first sentence uses an en dash correctly between '3' and '2'. A hyphen or spaced dash is not standard for ranges. More on this at .
Which sentence correctly places punctuation with a quotation that is a question?
She asked, "Where are you going?"
She asked, "Where are you going?".
She asked "Where are you going?".
She asked, "Where are you going?"!?

Which sentence correctly uses a semicolon and comma with a conjunctive adverb?
I wanted to leave however, it was raining.
I wanted to leave; however, it was raining.
I wanted to leave however; it was raining.
I wanted to leave, however; it was raining.
A semicolon should precede a conjunctive adverb, followed by a comma. The second option correctly places '; however,' to join the clauses. Other options either misuse commas or semicolons. See for more.
Which sentence correctly punctuates a sentence that ends with parentheses?
She finally responded, after a long pause).
She finally responded (after a long pause.)
She finally responded after a long pause).
She finally responded (after a long pause).

For breakfast, I had eggs, bacon, and toast, for lunch, salad, soup, and bread.
For breakfast, I had eggs, bacon and toast; for lunch, salad, soup and bread.
For breakfast, I had eggs, bacon, and toast; for lunch, salad, soup, and bread.

Which sentence correctly uses em dashes?
My friend - who is a doctor - arrived early.
My friend - who is a doctor - arrived early.
My friend--who is a doctor--arrived early.
My friend - who is a doctor - arrived early.

Which sentence correctly punctuates a book title within a sentence?
I just finished reading "To Kill a Mockingbird."
I just finished reading "To Kill a Mockingbird".
I just finished reading To Kill a Mockingbird.
I just finished reading 'To Kill a Mockingbird'.

She invited her parents, Oprah Winfrey and Barack Obama.
She invited her parents Oprah Winfrey and Barack Obama.
She invited her parents, Oprah Winfrey, and Barack Obama.
She invited her parents Oprah Winfrey, and Barack Obama.
The Oxford comma appears before the conjunction in a list of three or more items to avoid ambiguity. The second option correctly includes the comma before 'and'. The first option could imply the parents are Oprah and Barack. More on this at .
Which sentence correctly uses nested parentheses and brackets?
The requirements (see Appendix A [pages 10 - 12]) are clear.
The requirements (see Appendix A [pages 10-12] are clear).

Choose the sentence that uses an en dash and an em dash correctly.
The New York - London flight - rated five stars - was delayed.
The New York-London flight - rated five stars - was delayed.
The New York-London flight - rated five stars - was delayed.
The New York - London flight - rated five stars - was delayed.
An en dash connects ranges or partnerships (New York - London) and an em dash sets off parenthetical statements - like ' - rated five stars - '. The first sentence applies both dash types correctly. Other options mix hyphens and spacing improperly. See .

Cheat Sheet

  1. Comma Essentials -

    Mastering commas is crucial for clear writing and acing any punctuation quiz, especially when separating items in a list (e.g., "We need eggs, milk, and flour"). Use commas after introductory phrases (FANBOYS = for, and, nor, but, or, yet, so) to avoid run-ons. A handy tip: if you can say "pause" naturally in speech, a comma is likely needed.

  2. Semicolon Savvy -

    Semicolons link two independent clauses without a conjunction (e.g., "She loves reading; he prefers writing"). They also clarify complex lists (e.g., "Attendees: John Smith, CEO; Sarah Lee, CFO; and Mark Brown, COO"). Remember the rule from Purdue OWL: use semicolons when commas alone might confuse the reader.

  3. Colon Confidence -

    Use a colon to introduce lists, quotations, or explanations (e.g., "Bring three things: a pen, a notebook, and curiosity"). In formal writing and punctuation marks quizzes, colons also precede ratios and time (e.g., "3:45 PM" or "2:1"). A simple mnemonic: "What follows the colon is telling more."

  4. Apostrophe Accuracy -

    Apostrophes show possession (e.g., "the student's book") or form contractions (e.g., "it's = it is"), but never for plurals. A quick check: if you can replace the apostrophe word with "it is," it needs the apostrophe. Refer to the Chicago Manual of Style for in-depth examples and avoid a common error in many a punctuation test.

  5. Hyphen & Dash Distinction -

    Hyphens (-) join words in compounds (e.g., "well-being"), while en dashes ( - ) indicate ranges (e.g., "pages 10 - 20") and em dashes ( - ) set off parenthetical thoughts. The MLA Handbook recommends em dashes without spaces for strong breaks in a sentence. Remember: hyphens stick words together; dashes break thoughts apart.
