Question about "at" and "in" prepositions
My teacher told me that "at" is used with verbs that (more or less) indicate location, whereas "in" is used with more active verbs that describe things that occur as part of the lesson.

I'm not sure if there is a specific rule in this two prepositions.

e.g

i am good "at" chinese. why dont you use "in"?

"in/during" the lesson why not "at"
