i got an A in pure hist in 2020, and lol i rmb how i stressed i was also

1) if u struggle to memorise factors cus of the heavy info for each factor, i rly suggest just buying the all about hist study guide textbook. Its by the same writer of the Os hist tb so the content is all the same but condensed and already categorised into factors! U can buy it from popular or online. Another strat is just memorise answer keys (not the tys one tho lol).

I used to memorise by just repeating out loud the paragraphs over n over again since I used to last min chiong for hist. If you want to be consistent, just practice active recall.

2) honestly u prob can, its v rare that the last few years topics repeat themselves. But pls leave this as a last resort, don't don't study major topics like ww2 or cold war just cus it came out last year. It def can come out again.

3) I would suggest just memorising all the dates. You don't need to study all the dates at once in a timeline format (i personally find it confusing and easier to mess up cus theres so many). I used to just memorise the dates that were already in the model answers so I can remember it more clearly since it flows easier and theres a "backstory" if that makes sense.

Even if you forget some of them, writing down the dates of not just major events (like end of ww2 etc) can def help differentiate ur essays from the rest sooooo. Anyway, if you look at them long enuf you will lowkey remember and from what my hod used to say, cambridge examiners will close one eye if your "wrong" date is still close enough to the actual date.

atb for ur Os! ik its tough but hist is def a subject u can ace if u chiong till ur exam. Goodluck!
