Class, lesson, or course
A class is a group of students or a session, a lesson is what is taught in one session, and a course is the whole series of classes.
Quick rule
Meaning the students? Class. The topic of the day? Lesson. Everything that lasts weeks? Course.

A unit of teaching: what is taught in one session, or private teaching such as piano lessons.
A series of classes on one subject, with a start and an end, lasting weeks or months.

Why it trips people up
A course is the whole programme, a lesson is one unit inside it, and a class is the group or the meeting where it is taught. They get mixed up because one school day can involve all three at once.
