Question

I want to improve the usages of prepositions and ask my teacher for it. Is it okay if I say this to him

"Could you organise a class about how to use prepositions correctly?"

Answer

Your sentence is mostly correct, but a small adjustment would make it more precise:

"Could you organize a class on how to use prepositions correctly?"

This version maintains the same meaning while using the preposition "on" to indicate the topic of the class. Your original sentence is understandable, but using "on" instead of "about" in this context is more idiomatic.

Answer

Could you please organize a class on "How to use Prepositions correctly?"
