Is it permissible to review a portion of the exam questions disclosed by the professors (Hindus), given that the cheating was not on my part, and that not reviewing them could lead to failure?

Do not command the closing of ears from hearing explanations of exam questions. Rather, this act should be condemned by the heart, and an attempt should be made to convince the teachers to refrain from this behavior. If that does not help, then the issue should be presented to the administration.
