I assume you are referring to possessives. Possessives are not difficult, but there is wide misuse of the apostrophe in possessives. The possessive singular of all English nouns, regardless of spelling, is formed by adding -'s. In the case of nouns already ending in s, this adds a syllable to the pronunciation. The possessive of all English plural nouns ending in s is formed by adding the apostrophe alone, and there is no change in pronunciation.
Do not use the apostrophe alone for singulars ending in s. This ignorant practice is common in the media, but invariably incorrect.
These are correct:
Mary's book
students' schedules
Mrs. Smith's car

James' s Basketball
For ease of use (it is said) apostrophe conventions differ for some commercial purposes, e.g., titles of some movies and some large billboard advertisements. There, they omit a needed s. Personally, I think that is bad practice.
If, by chance you are referring to nominative plurals, you are making things too difficult. No nominative plural has an apostrophe: books, worms, students, shoes, computers.

To make a word that ends in a vowel plural, add -s to the end of the word. For example, "photo" becomes "photos" in the plural form.
