h2 history materials

im not planning to take h2 hist but i was curious about the content covered so i went on holy grail to find and couldnt find any notes 😭😭 they were all practice papers

is there a textbook or any good assessment book h2 history takers can rec me? i see most notes on carousell cost money 😔😔 h1 is also fine im just really bored while waiting for school to start
