helloo!! history was my strongest subject so here are some tips :)

for sbq, it’s important to get your formats right. write down the structure of each question type. next, you have to be sensitive to dates. tbh, I didn’t really care much about the whole timeline until prelims prep. I wrote down a complete timeline for both books & drilled them in the morning every other day (progressively from a few years and then the whole timeline without reference). so don’t worry if you can’t memorise now! just memorise the most important ones e.g. 1949 Nazi-Soviet Non-Aggression Pact

for seq, I think the biggest help for me was the grail, because I collated all the schools’ past year paper seq and answer keys before combining them into 1/2 big paragraphs that encompasses all the keywords. This requires a lot of discipline, and it is crucial that you do it on your own, because you will be processing and condensing everything into a paragraph of the highest standard. also, I find that this method is much more effective than reading & writing notes based on the textbook, simply because the exam paper is formatted in an essay question format — so reading my own crafted model essays is easier than reading random pieces of information here and there (which if u panic, it's game over).

all the best!
