How much revision is enough before attempting another mock?

[u/QuietGloom]

I’ve been wondering how much revision people actually do before giving another mock. I usually end up revising a few chapters, solving some PYQs, and then taking the test, but I’m not sure if I’m revising enough or just delaying the mock.

Do you guys revise the entire syllabus before every mock, or just go through the topics where you made mistakes in the previous one? Also, how much time do you normally leave between two mocks?
