i have 3 history exams too on edexcel!
so the first one we have is crime and punishment,if you do it, and honestly i suggest that you skip all of anglo saxon ect and start with the hardest stuff so the pages starting on vagabonds ect..
get the hardest stuff out of the way and make sure you spend time understanding them, you also dont need to know everysingle date in crime and punishment. just know the centuries they were established as crime and punsihment isnt really dates.
idk if you do british america and elizabethan but try and do as much as you can but the dates for both are necessary.
weimar shoulnt be too bad and you can revise that in a week
