I need help how to properly punctuation a sentence

Endmarks: All sentences need an endmark: a period, question mark, exclamation point, or ellipsis. Never put two endmarks at the end of the same sentence.

Apostrophes: For singular ownership, generally add’s; for plural ownership, generally add s’.

Commas: In direct address, use commas to separate the name from the rest of the sentence. In lists, place commas between items in a list, but not before the first item. Before conjunctions, when combining two complete sentences with a conjunction, place a comma before the conjunction. If you have one subject and two verbs, don’t put a comma before the conjunction.

Hyphens: If two words create a single description, put a hyphen between them if the description comes before the word that it’s describing. Don’t hyphenate two-word descriptions if the first word ends in -ly.

Colon: Use a colon after an independent clause that precedes a list and to separate an explanation, rule, or example from a preceding independent clause.

Semicolon: Use a semicolon to join independent clauses in compound sentences that do not have coordinating conjunctions (and, or, but, nor, for, so, yet) and commas as connectors. Words like however, moreover, thus, and therefore, are often used as connectors in these sentences. You can also use semicolons to separate long or complicated items in a series that already includes commas, and to separate two long or complex independent clauses joined by a coordinating conjunction if confusion would result from using a comma.

either online or traditional classroom can work for students. which is better will depend on students and teacher. students may have trouble following a lesson in classroom while they can study at their own pace online. other students may have trouble staying focus on their own in online classes. teachers are more used to classroom teaching but they may also be more worry about their jobs teaching online classes and work harder.
