hello!
i suppose it depends on the subjects you're doing as well as your confidence+understanding in said subject. i personally have found that re-writing my summary notes helps me recall information faster, which is especially important for content heavy subjects like bio and chem since it pretty much acted as a reintroduction or 'jump' back to a particular topic that i may have forgotten about.
in regards to math though, i feel that your time would be better spent improving your current bound reference/summary notes (e.g. ensuring that you have all of the relevant information, clarifying the meaning of specific terminology to that topic, etc) while also completing practice questions and problems as this will allow you to get used to the style of questions and 'speed up' while writing your answers/responses - something that i found really helpful while i was
stressing revising for my mid year exams
from a different perspective though, a friend of mine didn't really find rewriting summary notes to be that effective - which is valid tbh since it
might be a waste of your time if you just spend hours on formatting it to look 'pretty' or end up throwing in blocks of text that you won't be able to discern anything from.
tl;dr, summary sheets can be helpful, but be mindful of the time+effort it takes for them to be useful for u
i hope this made some sense lmao - good luck with revision!
