Does anyone know which questions from past exams are relevant?

I feel like somebody made a thread aabout this already but i cant seem to find it.

For 2021 curriculum, is there any trusted source providing the relevance of the past exams? Schweser and IFT contradict each other in many questions.

Thank you.

anyone?
