Creating custom tutorials is how The Grammar Project teaches. Each tutorial is a list of questions divided into lessons. Answer the questions in a lesson correctly three times and move on to the next lesson. When all the lessons are complete the tutorial is finished.
Tutorials can be created in a variety of ways. When you view a word, phrase or pattern, there is a “Learn” button on the page that will create a tutorial for that specific word, phrase or pattern. Or create a larger tutorial from one of the vocabulary lists or by flagging up to 200 words and phrases. You can also create a tutorial by ripping the words and phrases out of a piece of text.
