"In, On and At" as Prepositions of Place and Time
In this video, I teach you the basics of the correct usage of these three confusing prepositions. I must say that they are the most often misused prepositions in the English language (even by native speakers). I hope you find it useful, as I took as many notes possible, to simplify this topic for your better understanding. If you have any questions, please feel free to leave them in the comments section. I will be more than happy to answer them ASAP.
