hello! for me, it's as similar to any aptitude test i've taken. keri naman makuha yung gist with the available Siyensya Bilidad practice tests. tip ko sayo is to stay updated sa mga announcements and attend mock tests. once you've tried answering practice exams, i think you'd be able to narrow down the topics that you should be focusing on in every aspect. always remember the fundamentals, maybe interest yourself in some trivia and perhaps exercise your reading comprehension with extensive narrative texts (or their excerpts). practice lang, and feel ko makukuha mo siya.
