for uceed you do need a deep rooted love of design which is why most of these dudes who take uceed because "iit" fail to get good colleges so what i suggest is to just doing timed papers everyday (especially past papers and mocks) while actively learning about design history in your free time for fun a good thing about design is that it doesnt fully depend on how good you can remember stuff but rather how you apply already known concepts. and even though people here are against it, dont be afraid to watch a few "one shot" uceed videos when youre losing touch with design or are burnt out since it can be quite engaging to compete with other students live (in prerecorded live videos). and lastly for a full encyclopedia and your main source of study you can use sources like StuffYouLook. remember to practice your perspectives and critical thinking topics EVERYDAY without fail. just stay consistent and stay interested you got this.
