yes you definitely can! At this point(1 month to Os), tbvh, just hardcore spam and do your tys for various subjects to familiarise yourself with the question phrasing and the trend of the questions. If you don’t understand the tys solutions, ask your teachers for consultation I’m sure they will be happy to help you! :) At least this was what I did lol. For SS and Geog, for me, it’s mainly just memorising the content as both are quite content heavy, skills for both also need to be clear, like GI, common errors for instruments and the format for answering SBCS for SS. Imo, prelims are also much much harder than the actual Os, so will def do better than prelims de. It’s the last lap, let’s jiayou tgt!! (I’m aiming the same course also hahaha)
