How should i go about it then? Bc i kinda enjoy the gameplay loop and don't wanna give up just yet. When i heard "trial of mind" i'd assume i needed high prowess, knowledge, imagination stat, practise spells, go dueling class or sport and get a few equipment in shop. I tried memorising the answers for the trial but thats hopeless if i need specific stats. Every playthrough It is so difficult priortising at least 61% knowledge for exams and working on other stats and money for items
Your assumption was correct. There are several ways to win the trial and the key is knowing which door prefers which stat (efrfrf34 wrote about that), but all doors can be opened in several ways. Play to your character's strengths. But most importantly, you don't really need to win every trial to progress or even win the Cup, so just enjoy yourself :)
