I do not understand this (younger generation) need for question banks. The purpose of an examination is to find, by asking a number of selected questions, if you know and understand the material detailed in the syllabus. . To know and understand the material in the syllabus you need to study that material and probably also engage with others who have the knowledge and experience to tutor you.
To my mind trying to "pass" by learning from a bank of potential questions is highly unprofessional.
Would you apply the same process to the practical skills of flying?
