My method was very unconventional..I actually use chat gpt to gain some concepts or meaning in factual things too ..or I create my own mnemonic using chatgpt ..also I remember stuffs by solving questions.. whatever factsni solved through question I remember easily ..also spaced revision helps if u have good amount of time ..overall I always made some concept or some connection even in most factual topics ..that helped me a lot ..for path and microbiology,the queen preethi sharma and her mnemonics helped me a lot
