Ouch on the slaves, there. You will really need to learn it, but I feel you might be exaggerating when you say you don’t know any of it. There’s a while unttil the exam tho’.
BBC bitesize notes are quite good to jog your memory, so perhaps mindmap the topic from this and try past paper questions on the different sections - even mindmapping these I sometimes feel is better than just sitting down practicing them. Guess I’m a mindmap enthusiast ¯\_(ツ)_/¯
For nine markers there tends to be a sort-of formula that once you get the hang of it flows easily.
Start with the intro, giving background and introducing the arguments. “X happened for many reasons. One reason was blah, however the impact of blah also contributed. “
Then do the body, which consists of 5 points across two or three paragraphs (eg one containing three another containing 2 is ideal). Begin each para with a sentence to introduce the factor “Some historians argue the main reason was blah.” Might help to give context too if you have any, Idk if that is given marks.
The points in each paragraph work basically the same way as an answer to an explain question does. You give your reasons and explain exactly how or why they had whatever impact.
The conclusion is pretty simple as it has just two parts: you make your overall conclusion I guess in one sentence then sum up in anothed, explaining the judgment.
Hope I’m helping, truth is I’m dead tired and hardly functioning atm. Sorry if this turns out to be at all incoherent.
All the best.
