A student wrote to me the other day to ask about an IELTS book that she had bought. The book contained tips that were completely different from the tips that I give. The student felt confused and wanted to know which tips were right.
I see this problem all the time. Students use different books and websites that contain different tips and methods. The resulting confusion hinders* students instead of helping them.
Here's my solution to this problem: stop using so many different books and websites! Choose one website, or one book, or one teacher, and follow one consistent method. If you read contradictory advice in a different book, ignore it - it's just a different method.
*to hinder = to stop someone or something from making progress
