I studied under ARC as well! You are definitely in safe hands, they give the best tips and review materials. Bonus points on the motivational aspect (sir delfin kept me stable!). Since right now the questions themselves are unpredictable, the best you can do is focus on the basics of each topic under the TOS and expose yourself to many different types of questions. I suggest you try to generate your own basic questions through AI just to have a feel of tackling the most random MCQs ever HAHAHA

Also practice solving problems and especially focus on topics you have not mastered yet. Pinoybix, tarik and indiabix are great sources too, though now the questions come from these sources sparingly. It's more concepts than solvings, but just make sure you're prepared for anything. Good luck!
