The tutorial system is a method of university education where the main teaching method is regular, very small group sessions. These are the core teaching sessions of a degree, and are supplemented by lectures, practicals and larger group classes.
Tutorials are often not optional because they give you an opportunity to delve deeper into concepts, and attendance may contribute to your participation mark
A tutorial can be taken in many forms, ranging from a set of instructions to complete a task to an interactive problem solving session (usually in academia).
In documentation and instructional design, tutorials are teaching-level documents that help the learner progress in skill and confidence. Tutorials can take the form of a screen recording (screencast), a written document (either online or downloadable), interactive tutorial, or an audio file, where a person will give step by step instructions on how to do something.
