Yes. The experiences belong to the students, so it needs an apostrophe. However, since it is plural, you put it after the final s. So, Most students' experiences...
The correct way to write the sentence is: "The students' books are on his desk." The apostrophe is placed after the "s" in "students" to show that the books belong to the students.
"Students' is used with an apostrophe at the end when it denotes possession by multiple students. For example, 'The students' desks were arranged in rows'."
Ten students' grades were below passing.Ten students' grades had improved.Here grades is a plural common noun and needs no apostrophe.Students is a plural common noun.

Neither one. The apostrophe indicates possession or ownership. It would be plain students, with no apostrophe.
That depends upon what you are trying to say. The plural of student is students, no apostrophe. If you wish to say that something belongs to a particular student, then it is the student's (book, or whatever). If you wish to say that something belongs to a group of students, then it is the students' (school, or whatever).
An apostrophe indicates possession or attribute (something about a noun).The singular is student's -- belonging to a student (e.g. the student's locker).The plural is students' -- belonging to more than one (e.g. the students' lockers).
Mikes needs an apostrophe. So the sentence would be: "Mike's car needs a new muffler and new brakes."
A possessive noun needs an apostrophe: The clerk's pen (common noun, singular); The students' notebooks (common noun, plural); Jane's wallet (proper noun). A possessive pronoun has no apostrophe: Your pen; Our notebooks.
That depends on how you're trying to use the word. See the sentences below for examples: 1) I have 30 students in my class. 2) I have 30 students' books in my class. 3) I have this student's homework slip. Sentence one has an S because it is indicating plurality. Sentence two has an apostrophe after the S because it is indicating plurality and possession. Sentence three has an apostrophe S because it is indicating singular possession.
You don't need an apostrophe in that sentence. Studentsis a plural word, not a possessive.
