hi there! this is the perfect question for me as a film student at uni paha. i was predicted an A* in eduqas film studies and i did very similar films to you 🙂
my biggest life saver was quizlet - a lot of people created flashcards for those films especially! you can filter them out and write notes from quizlet. but the best way i personally revised was looking at past questions. most of the time, especially for paper one, they ask you for one sequence to demonstrate your points. so this is what you do very early on. the questions themselves hardly change - for example for casablanca (paper 1, section a, one of the questions will always be “production contexts” so i wrote practice essays. i memorised the same essay for that question. similar to the silent film question (paper 2, section c), it will most likely be gender or realism, so you choose early on which one you want to do and you memorise an essay.
if that’s a bit much for you, you can always make flash cards for each film - one that has the director, year, country, actors, style, genre etc, and another that has at least one key sequence on it. for casablanca, this could be the paris sequence, and you list every technique (sound, cinematography, mise en scene, editing) used that you think is relevant and you would like to include in your essay. this i would say is the best way to do it. if flashcards don’t work, mindmaps are just as fun!
for certain questions, you can use this guide:
hollywood film - how do your two films reflect their production context? big five, vertical integration, classical hollywood vs new hollywood etc and then a key sequence from each film
american film - which ideologies are prominent in your chosen films? do you think the audience accepts or rejects them (passive or active audience)? two sequences that reflect these ideologies (choose two scenes from each film which perhaps have opposing ideologies)
british film - what makes this film british? how does it follow british conventions? generational conflict, skinheads vs fascists, drug culture, etc and then again a key sequence from each film (they love to focus on the opening or ending scenes so pay close attention to these and their narrative theories - are they todorov or not?)
international film - how do these films reflect their contexts? which issues are raised and what techniques do they deploy to show them? they may also ask about aesthetic - choose a sequence from each film with unique styles/represent issues
documentary - what digital technology is used to produce your film? what filmmakers’ theories are shown in your film? (usually colleges only teach you to answer one of these) - use the theories you are taught in class😌 again choose a sequence to illustrate this
silent film - expressionism vs realism - which one is your film? use techniques that are deployed to illustrate this and again choose a sequence to show it (maybe choose a few) but remember you’re doing multiple films so one may stand out as more realistic than the others or more expressionistic
experimental - what experimental techniques are used? choose a sequence to demonstrate this
hope this helps! again make sure to check quizlet if you’re struggling - but also check the educas website. they have fact sheets for every film!
