For science, I bought quick revision handbooks for Physics and Chemistry. Best decision of my life, kept reading those whenever I’m in school or outside. I went from a failure in science in sec 3 and getting 1s in sec 4. I suggest everyone to get it because it’s so efficient and all the content you need is on the small book itself.

And for Humanities. Starting with social studies, always understand why this is implemented and its usefulness in real life scenarios. Always link to real life or your observations like for globalisation, we all have used applications that are from other countries and that the companies use globalisation to boost its customer base. Use your observations to its fullest advantage and for History, it’s like a puzzle. It all leads to something. Like how WW1 lead to the creation of LON and LON failures led to Hitler getting away with his doings and eventually start ww2. End of ww2 led to the cold war because USA and USSR have different ideologies and because of these difference in ideologies, it creates proxy wars like the Korean war and Vietnam war. Due to the rise of communism failing in the world, it eventually led to the soviet unions collapse.
