please revise something!
go over how to analyse language, how to include context, key language... even minor things! it's possible that the revision of even one important term will save you that time thinking of how and what to write.
but, back to the actual question... it really depends on the content. if you're the type of person that retains a lot and is well-off even without revision, it's possible you could get a B. but if not... i suggest you revise lmao
