Adjectives used to indicate obligation

Many students have difficulties when using adjectives to indicate obligation, perhaps confusing the form used in passive voice structures with the form more commonly associated with adjectives.

Instead of the more commonly used It is form, students tend to use You are:

You are compulsory to attend school every day.

Actually, you are unnecessary to tolerate the severe requirement of the triad members and to make friends with them. (TeleNex Students)
