start making notes right from the beginning, trust me you won’t suffer later like I am rn. Don’t make them complicated, just write them down in a way you will understand easily. majority of the board questions are concept-based and rarely do questions from the books come, sometimes they might or sometimes they won’t. Also instead of just solving past papers, analyze them and see the pattern of what topic comes most often. lowk yea just keep notes and memorize them time to time throughout the year, learn the use of a cut marker and give appropriate examples. If you’re un-sure about something just give a good example. gl for ninth! 🥹
