Correct Usage of Who and Whom in Questions

The video tutorial explains the correct usage of 'who' and 'whom' in sentences. 'Who' is used as a subject pronoun, while 'whom' is used as an object pronoun. A simple trick to remember the difference is to substitute 'he' or 'him' in the sentence; if 'he' fits, use 'who', and if 'him' fits, use 'whom'. The tutorial includes examples and exercises to practice this rule, and a letter revision task to apply the knowledge. The lesson concludes with a review of the key points.
